  • Information about rendering, batches, the graphical card, performance etc. + XNA?

    - by Aidiakapi
    I know the title is a bit vague but it's hard to describe what I'm really looking for, but here goes. When it comes to CPU rendering, performance is mostly easy to estimate and straightforward, but when it comes to the GPU due to my lack of technical background information, I'm clueless. I'm using XNA so it'd be nice if theory could be related to that. So what I actually wanna know is, what happens when and where (CPU/GPU) when you do specific draw actions? What is a batch? What influence do effects, projections etc have? Is data persisted on the graphics card or is it transferred over every step? When there's talk about bandwidth, are you talking about a graphics card internal bandwidth, or the pipeline from CPU to GPU? Note: I'm not actually looking for information on how the drawing process happens, that's the GPU's business, I'm interested on all the overhead that precedes that. I'd like to understand what's going on when I do action X, to adapt my architectures and practices to that. Any articles (possibly with code examples), information, links, tutorials that give more insight in how to write better games are very much appreciated. Thanks :)

  • Higher Performance With Spritesheets Than With Rotating Using C# and XNA 4.0?

    - by Manuel Maier
    I would like to know what the performance difference is between using multiple sprites in one file (sprite sheets) to draw a game-character being able to face in 4 directions and using one sprite per file but rotating that character to my needs. I am aware that the sprite sheet method restricts the character to only be able to look into predefined directions, whereas the rotation method would give the character the freedom of "looking everywhere". Here's an example of what I am doing: Single Sprite Method Assuming I have a 64x64 texture that points north. So I do the following if I wanted it to point east: spriteBatch.Draw( _sampleTexture, new Rectangle(200, 100, 64, 64), null, Color.White, (float)(Math.PI / 2), Vector2.Zero, SpriteEffects.None, 0); Multiple Sprite Method Now I got a sprite sheet (128x128) where the top-left 64x64 section contains a sprite pointing north, top-right 64x64 section points east, and so forth. And to make it point east, i do the following: spriteBatch.Draw( _sampleSpritesheet, new Rectangle(400, 100, 64, 64), new Rectangle(64, 0, 64, 64), Color.White); So which of these methods is using less CPU-time and what are the pro's and con's? Is .NET/XNA optimizing this in any way (e.g. it notices that the same call was done last frame and then just uses an already rendered/rotated image thats still in memory)?

  • What is the fastest way to compare 2 rows in SQL?

    - by Swoosh
    I have 2 different databases. Upon changing something in the big one (i don't have access to), i get some rows imported in my databases in a similar HUGE table. I have a job checking for records in this table, and if any, execute a stored procedure, process and delete from table. Performance. (Huge amount of data) I would like to know what is the fastest way to know if something has changed using let's say 2 imported rows with 100 columns each. Don't have FK-s, don't need. Chances are, that even though I have records in my table, nothing has actually changed. Also. Let's say there is actually changed something. Is it possible for example to check only for changes inside datetime columns? Thanks

  • Oracle SQL: Multiple Subqueries Unioned Without Running Original Query Multiple Times.

    - by Bob
    So I've got a very large database, and need to work on a subset ~1% of the data to dump into an excel spreadsheet to make a graph. Ideally, I could select out the subset of data and then run multiple select queries on that, which are then UNION'ed together. Is this even possible? I can't seem to find anyone else trying to do this and would improve the performance of my current query quite a bit. Right now I have something like this: SELECT ( SELECT ( SELECT( long list of requirements ) UNION SELECT( slightly different long list of requirements ) ) ) and it would be nice if i could group the commonalities of the two long requirements and have simple differences between the two select statements being unioned.

  • Very large database, very small portion most being retrieved in real time

    - by mingyeow
    Hi folks, I have an interesting database problem. I have a DB that is 150GB in size. My memory buffer is 8GB. Most of my data is rarely being retrieved, or mainly being retrieved by backend processes. I would very much prefer to keep them around because some features require them. Some of it (namely some tables, and some identifiable parts of certain tables) are used very often in a user facing manner How can I make sure that the latter is always being kept in memory? (there is more than enough space for these) More info: We are on Ruby on rails. The database is MYSQL, our tables are stored using INNODB. We are sharding the data across 2 partitions. Because we are sharding it, we store most of our data using JSON blobs, while indexing only the primary keys

  • Antivirus Configuration for dedicated SQL and dedicated IIS Servers

    - by Wayne Arthurton
    Our corporate standard is McAfee Enterprise, unfortunately this is non-negotiable. On two types of servers I'm responsible for, SQL & Web, we have noticed major performance issues with the corporate standard setup. Max scan time 45sec One policy for all processes Scan ALL files on write, read and open for backup Heuristics: Find unknown programs, trojans and macros Detect unwanted programs Exclude: EVT, LDF, LOG, MDF, VMD, , windows file protection) This of course still causes major slowdowns. IIS .NET recompiles are slow especially with SharePoint, SQL backups and restores, SQL Analysis Services, Integration Services and temp data from them as well. I have looked from time to time, for some best practices on setting up McAfee of SQL & SQL Analysis Service, SQL Integration Service, Visual Studio, Sharepoint, and .NET web servers in general. How do people setup McAfee enterprise on their corporate serves keeping security intact, but affecting performance as minimally as possible? Has anyone run across white papers on these setups? Obviously some are case by case, but there must be some best practices out there somewhere.

  • Oracle SQL Developer version 3.2.2 Released

    - by thatjeffsmith
    This is another maintenance release, but I don’t want to minimize the work done in either the 3.2.1 or the 3.2.2 editions. The two releases include more than 400 bug fixes. Version 3.2 should be rocking and rolling and good to go while we work on the next major release! You can find the downloads and bug fixes in the normal places: Download 3.2.2 Bug fixes Connection Names If you downloaded and used version 3.2.1 and noticed some of your connection names were no longer valid due to ‘special’ characters, we’ve loosed our restrictions a bit for 3.2.2. You can now go back to using spaces and hyphens in your connection names. periods, spaces, hyphens should now all work More Copy & Paste Stuff While fixing a bug, the developer decided to also enhance the feature while he was in the code. I love seeing this happen organically. No one is sitting over their shoulder with the red magic marker. No, I’m too far away to do that except on very special days So here’s a ‘trick’ – if you want to copy cells from your grids, just drag the selected cells to the worksheet/editor. You’ll get a comma delimited list – very handy! Select cells, drag and drop up to the worksheet – Voila! Comma separated values

  • Justifying a memory upgrade

    - by AngryHacker
    My employer has over a thousand servers (running SQL Server 2005 x64 and a couple of other apps) all across the country. And in my opinion they are all massively underpowered for what they need to do. Specifically, I feel that the servers simply do not have enough RAM for the amount of volume the machines are asked to do. All the servers currently have 6GB of RAM. The users are pretty much always complaining about performance (mostly because, immo, the server dips into the paging file quite often). I finally convinced the powers that be to at least try out a memory upgrade on one box and see the results. However, they want before and after metrics, so that they can see that the expense will be justified. My question is what metrics should I collect to see whether the performance truly improves on the box? I am a dev, so I am not sure how and what to collect (i have a passing knowledge of Perfmon).

  • Bad Performance when SQL Server hits 99% Memory Usage

    - by user15863
    I've got a server that reports 8 GB of ram used up at 99%. When restart Sql Server, it drops down to about 5% usage, but gradually builds back up to 99% over about 2 hours. When I look at the sqlserver process, its reported as only using 100k ram, and generally never goes up or below that number by very much. In fact, if I add up all the processes in my TaskManager, it's barely scratching the surface of my total available (yet TaskManager still shows 99% memory usage with "All processes shown"). It appears that Sql Server has a huge memory leak going on but it's not reporting it. The server has ran fine for nearly two years, with this only starting to manifest itself in the last 3-4 weeks. Anyone seen this or have any insight into the problem? EDIT When the server hits 99%, performance goes down hill. All queries to the server, apps, etc. come to a crawl. Restarting the service makes things zippy again, until 2 hours has passed and the server hits 99% once again.

  • Can’t connect to SQL Server 2008 - looks like Shared Memory problem

    - by user38556
    I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio. I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Why is it returning a Named Pipes error? Why would it not just use Shared Memory, as this has a higher priority order in the list of connection protocols? It seems like it is not listening on Shared Memory for some reason? When I set Named Pipes to enabled and try to connect, I get the same error message. My windows account is does not have administrator priviliges on my computer - perhaps this is making a difference in some way (as some of the discussions in this post about an "SuperSocketNetLib\Lpc" registry key seems to suggest). I have tried restarting the SQL Server service, by the way, and also tried to get someone to log onto the machine with an admin account to restart the SQL Server service. Still no luck.

  • SQL Developer Data Modeler: On Notes, Comments, and Comments in RDBMS

    - by thatjeffsmith
    Ah the beautiful data model. They say a picture is worth a 1,000 words. And then we have our diagrams, how many words are they worth? Our friends from the Human Relations sample schema So our models describe how the data ‘works’ – whether that be at a logical-business level, or a technical-physical level. Developers like to say that their code is self-documenting. These would be very lazy or very bad (or both) developers. Models are the same way, you should document your models with comments and notes! I have 3 basic options: Comments Comments in RDBMS Notes So what’s the difference? Comments You’re describing the entity/table or attribute/column. This information will NOT be published in the database. It will only be available to the model, and hence, folks with access to the model. Table Comments (in the design only!) Comments in RDBMS You’re doing the same thing as above, but your words will be stored IN the data dictionary of the database. Oracle allows you to store comments on the table and column definitions. So your awesome documentation is going to be viewable to anyone with access to the database. RDBMS is an acronym for Relational Database Management System – of which Oracle is one of the first commercial examples If the DDL is produced and ran against a database, these comments WILL be stored in the data dictionary. Notes A place for you to add notes, maybe from a design meeting. Or maybe you’re using this as a to-do or requirements list. Basically it’s for anything that doesn’t literally describe the object at hand – that’s what the comments are for. I totally made these up. Now these are free text fields and you can put whatever you want here. Just make sure you put stuff here that’s worth reading. And it will live on…forever.

  • Need help tuning Mysql and linux server

    - by Newtonx
    We have multi-user application (like MailChimp,Constant Contact) . Each of our customers has it's own contact's list (from 5 to 100.000 contacts). Everything is stored in one BIG database (currently 25G). Since we released our product we have the following data history. 5 years of data history : - users/customers (200+) - contacts (40 million records) - campaigns - campaign_deliveries (73.843.764 records) - campaign_queue ( 8 millions currently ) As we get more users and table records increase our system/web app is getting slower and slower .

  • Server configurations for hosting MySQL database

    - by shyam
    I have a web application which uses a MySQL database hosted on a virtual server. I've been using this server when I started the application and when the database was really small. Now it has grown and the server is not able to handle the db, causing frequent db errors. I'm planning to get a server and I need suggestions for that. Like I said, the db is now 9 GB, and is growing considerably fast. There are a number of tables with millions of rows, which are frequently updated and queried. The most frequent error the db shows is Lock wait timeout exceeded. Previously there used to be "The total number of locks exceeds the lock table size" errors too, but I could avoid it by increasing Innodb buffer pool size. Please suggest what configurations should I look for in the server I should buy. I read somewhere that the db should ideally have a buffer pool size greater than the size of its data, so in my case I guess I'd need memory gt 9 GB. What other things should I look for in the server? Just tell me if I should give you more info about the

  • Copying & Pasting Rows Between Grids in SQL Developer

    - by thatjeffsmith
    Apologies for slacking on the blogging front here lately. Still mentally hung over from Open World, and lots of things going on behind the scenes here in Oracle-land. Whilst (love that word) blogging is part of my job, it’s not the ONLY part of my job So a super-quick and dirty ‘trick’ this morning. Copying Query Result Record as New Row in Table Copy and paste is something everyone ‘gets.’ I don’t know we have to thank for that, whether it’s Microsoft or Xerox, but it’s been ingrained in our way of dealing with all things computers. Almost to the detriment of some of our users – they’ll use Copy and Paste when perhaps our Export feature is superior, but I digress. Where it does work just fine is when you want to create a new row in your table that matches a row you have retrieved from an executed query. Just click in the gutter or row number to get the entire row selected Once you have your data selected, do your thing, i.e. ctrl+C or Command/Apple+C or whatever. Now open your view or table editor, go to the data page, and ask for a new row. New record, no data Paste in the data from the clipboard. It’s smart enough to paste the separate values out to the separate columns. The clipboard saves the day, again. If your columns orders are different, just change the order in the grids. If you have extra information, don’t copy the entire row. I know, I know – Jeff this is too simple, why are you wasting our time here? It seems intuitive, but how many of you actually tried this before reading it just now? I seem to get more positive feedback from the very basic user interface 101 tips than the esoteric click-click-click-ctrl-shift-click tricks I prefer to post. Lots of interesting stuff on tap, so stay tuned!

  • Changing memory allocator to Jemalloc Centos 6

    - by Brian Lovett
    After reading this blog post about the impact of memory allocators like jemalloc on highly threaded applications, I wanted to test things on a larger scale on some of our cluster of servers. We run sphinx, and apache using threads, and on 24 core machines. Installing jemalloc was simple enough. We are running Centos 6, so yum install jemalloc jemalloc-devel did the trick. My question is, how do we change everything on the system over to using jemalloc instead of the default malloc built into Centos. Research pointed me at this as a potential option: LD_PRELOAD=$LD_PRELOAD:/usr/lib64/libjemalloc.so.1 Would this be sufficient to get everything using jemalloc?

  • Current wisdom on SQL Server and Hyperthreading?

    - by BradC
    Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

  • Organizing Connections with Folders in Oracle SQL Developer

    - by thatjeffsmith
    How many Oracle databases do you work with on a regular basis? I’m guessing the answer for most of you lies between 1 and 500. This post is really geared for those of you who deal with more than just a handful (5) of database connections. Filters are nice when you need to work with a subset of table data, or even a list of tables. So why wouldn’t they be just as useful for organizing your connections? Here’s my complete list of databases: The folders aren’t there by default, you add them as you need them. Now this isn’t an overly large connection list. But when I need to fire up an impromptu demo for a customer, it’s very nice to be able to drill down into JUST those ‘safe’ environments. This actually saves me a few seconds every time I need to connect to one of my databases. So while it’s a very simple feature, it’s one of those things that I recommend EVERYONE take advantage of as it will save them hours of time over the long haul.
