  • Does more RAM on Mac really improve performance?

    - by Moshe
    I'm coming from a PC, loaded with a Core 2 Quad CPU and 8GB of DDR2 RAM. I was running Premiere CS3. I'm new to Mac so I'm not sure if this will help performance: Will increasing my 21.5" Core 2 Duo iMac's memory from 4GB (DDR3) to 8GB improve performance of Premiere CS4 significantly? I am not impressed with Premiere as it is now. The iMac is the newest one as of this post.

  • Page Load Time and SEO

    Only a few months ago I was thinking of writing an article about how the relatively recent pervasiveness of broadband, high-speed Internet has changed the way sites are developed. It wasn't that long ago, when one of the major goals of designing a web page was to keep the entire thing under 30Kb. Now developers and designers are using background images that are larger than that - let alone the media rich content that fills the pages.

  • Comparing the Performance of Visual Studio&apos;s Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using <a href="http://www.4guysfromrolla.com/articles/120705-1.aspx">ASP.NET's Membership system</a> is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a <a href="http://www.4guysfromrolla.com/articles/100803-1.aspx">web service</a> generates markup that auto-creates a <i>proxy class</i>, which handles the low-level details of invoking the web service, serializing parameters,

  • Minecraft: Slow performance OUT of the game

    - by blackn1ght
    I downloaded Minecraft yesterday to see what the fuss is about, brilliant game! When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping? Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box. Any ideas? Ubuntu 10.10 x64 Intel Q9550 4GB RAM nVidia 8800GTS 320mb (w/prop drivers installed)

  • Desktop background will not load after performing aticonfig --adapter=all --ovt=opengl

    - by user1571959
    I am trying to get Eagle to work on ubuntu 14.04 LTS. When I run Eagle and open a schematic the display is not refreshing/redrawing correctly. One solution that I found was to install the flgrx drivers and do the aticonfig command to use opengl... So I did and rebooted. Now when I turn on my laptop I get all the way to the login screen, login, and then nothing happens, it just goes to the background image with no icons or anything... I tried deleting and copying the original xorg.conf file and no results... What do I do other than reinstalling Ubuntu? is there anyway to force the original driver?

  • PC noisy due to high load - why?

    - by Jinx
    I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it. How come? How to set it to be quiet again in unbuntu 10.04. One of the two cpu usage is always 100%. I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.

  • Oracle Database I/O Performance Tuning Using Benchmark Factory

    The real test of how heavily an Oracle database will tax its underlying I/O subsystem and related infrastructure is to actually tax that infrastructure using representative database application workloads. Jim Czuprynski tells you how to choose appropriate database schema(s) for realistic testing, how to create example TPC-E and TPC-H database schemas and how to perform initial loading of these schemas using Quest Benchmark Factory.

  • WHERE x = @x OR @x IS NULL

    - by steveh99999
    Every SQL DBA and developer should read the blog of MVP Erland Sommarskog – but particularly  his article on dynamic search conditions in T-SQL. I’ve linked above to his SQL 2005 article but his 2008 version is also a must-read. I seem to regularly come across uses of the SQL in the title above… Erland’s article explains in detail why this is inefficient, but I came across a nice example recently… A stored procedure contained the following code :- WHERE @Name is null or [Name] like @Name as a nonclustered index exists on the Name column, you might assume this would be handled efficiently by SQL Server. However, I got the following output from SET STATISTICS IO Table 'xxxxx'. Scan count 15, logical reads 47760, physical reads 9, read-ahead reads 13872, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Note the high number of logical reads… After a bit of investigation, we found that @Name could never actually be set to NULL in this particular example. ie the @x IS NULL was spurious… So, we changed the call to WHERE  [Name] like @Name Now, how much more efficient is this code ? Table 'xxxxx'. Scan count 3, logical reads 24, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0 A nice easy win in this case…… a full index scan has been replaced by a significantly more efficient index seek. I managed to recreate the same behaviour on Adventureworks – here’s a quick query to demonstrate :- USE adventureworks SET STATISTICS IO ON DECLARE @id INT = 51721 SELECT * FROM Sales.SalesOrderDetail WHERE @id IS NULL OR salesorderid = @id SELECT * FROM Sales.SalesOrderDetail WHERE salesorderid = @id Take a look at the STATISTICS IO output and compare the actual query plans used to prove the impact of  WHERE @id IS NULL. And just to follow some of Erland’s advice – here’s how you could get similar performance if it was possible that @id could actually sometimes contain NULL. DECLARE @sql NVARCHAR(4000), @parameterlist NVARCHAR(4000) DECLARE @id INT = 51721 – or change to NULL to prove query is functionally correct SET @sql = 'SELECT * FROM Sales.SalesOrderDetail WHERE 1 = 1' IF @id IS NOT NULL SET @sql = @sql + ' AND salesorderid = @id' IF @id IS NULL SET @sql = @sql + ' AND salesorderid IS NULL' SET @parameterlist = '@id INT' EXEC sp_executesql @sql, @parameterlist,@id Sometimes I think we focus too much on hardware and SQL Server configuration – when really the answer is focus on writing efficient SQL.

  • Google Analytics: Custom variables issue difference in data

    - by Bart
    We’ve set up tracking through custom variables in Google Analytics to measure which offices are getting the most traffic. The custom var consists out of the key (=office) and value = (office name). In our Custom Var tab in audience we get no data (actually we got 1 hit, but we think the data is way off). When we setup advanced segments with the filters on key and value we get the correct data. Now we are wondering why we aren’t getting that data in the custom var tab.

  • What is the average page size for single page application (SPA)? [on hold]

    - by Emmanuel Istace
    I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA? As this is the whole website, do you think it's acceptable? Is lazy load (for images) a solution? What will be impact for SEO ? Is the "200kb rule" of google still relevant? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs? Can a caching strategy be an answer?
