  • How to control fan speed using SpeedFan?

    - by John Young
    The CPU fan in my laptop is running too fast. I wish to control the speed manually to my preference, at times. Here is a CPU-Z screenshot of my laptop configuration: http://i.stack.imgur.com/1oST1.png And here is how SpeedFan window looks at my end: http://i.imgur.com/BIi0RdJ.jpg I have no idea how to use SpeedFan to control my laptop's CPU fan speed. How to configure it so that I can increase and decrease speed of the fan at my will? Edit: Sorry, the first image wasn't as intended, so I've corrected it now. Also, if someone can edit the post and embed the images in the post, that would be great. I need at least 10 reputation to successfully accomplish that.

  • limit the speed of writing files to NFS

    - by xgwang
    CentOS 5.6 NFS is mounted on the server for backup disk space. When the backup job started, it could reach 80MB/s and we really do not expect it took so much bandwidth. So i need to find a way to limit the speed of writing to NFS. I tried rsync with --bwlimit=5000. However, it did limit the reading speed, but the accumulated data still was written at 80MB/s, and no writing activities for seconds. Is there any way to limit the writing speed of NFS?

  • Sudden slow read & write speed on all IO

    - by user23392
    I have a custom built rig that has 2 storage drives. for OS: Western Digital 1.0TB HARD DR 64MB for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ] The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device. I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable. Here's my benchmark on the HDD ( read speed - write speed ): And the SSD: Anyone knows what could be the issue?

  • Strategies for very fast delivery of webpages.

    - by Cherian
    I run a website Cucumbertown with an initial pay load of nearly 9KB zipped. All my js is delayed loaded with requirejs and modernizer is the only exception. Now all my webpages are Nginx cached and only 10-15% hits go to the backend proxy. And the cache is invalidated by logged in users as proxy_cache_bypass. So for an anonymous user its nearly always a cache hit. I have some basic OS tuning with default via ip dev eth0 initcwnd 15 net.ipv4.tcp_slow_start_after_idle 0 Despite an all cache & large initcwnd my pages still take 2.5 – 3 seconds. I have a yslow score of And page speed at Are there strategies that can help deliver webpages even faster than this? Deliver pages at 1+ second time for 10KB payload? Notes: My servers run of a fairly good data center from Linode at Fremont.

  • What could be causing this long waiting time on page load?

    - by Andrew Findlay
    What could be causing a 1.18s wait time when my page loads? Just to make sure I did not have any conflicting or parallel scripts loading, I completely deleted all the script on my home page and ran the speed test again. Although I had a blank website and 5kb file size, there was still a 900ms "waiting" time. I'm wondering if it could be my server? Any other thoughts or suggestions as it doesn't seem to be scripts. EDIT - Just ran a DNS test on pingdom and here are my results. Does this tell me anything? No nameservers found at child?

  • Are there well-known examples of web products that were killed by slow service?

    - by Jeremy Wadhams
    It's a basic tenet of UX design that users prefer fast pages. http://www.useit.com/alertbox/response-times.html http://www.nytimes.com/2012/03/01/technology/impatient-web-users-flee-slow-loading-sites.html?pagewanted=all It's supposedly even baked into Google's ranking algorithm now: fast sites rank higher, all else being equal. But are there well known examples of web services where the popular narrative is "it was great, but it was so slow people took their money elsewhere"? I can pretty easily think of example problems with scale (Twitter's fail whale) or reliability (Netflix and Pinterest outages caused by a single datacenter in a storm). But can (lack of) speed really kill?

  • http requests, using sprites and file sizes -

    - by crazy sarah
    Hi all I'm in the process of finding out all about sprites and how they can speed up your pages. So I've used spriteMe to create a overall sprite image which is 130kb, this is made up of 14 images with a combined total size of about 65kb So is it better to have one http request and a file size of 130kb or 14 requests for a total of 65kb? Also there is a detailed image which has been put into the spite which caused it's size to go up by about 60kb odd, this used to be a seperate jpg image which was only 30kb. Would I be better off having it seperate and suffering the additional request?

  • What's an acceptable "Avg. Page Load Time"?

    - by hawbsl
    Is there any industry rule of thumb for what's considered an unacceptable load time v. an OK one v. a blistering fast one? We're just reviewing some Google Analytics data and getting 0.74 Avg. Page Load Time reported. I guess that's OK. However it would be good if some meatier comparison data were available, or a blog post, or somewhere where there's some analysis of what speeds are generally being achieved by various kinds of sites. Any useful links to help someone interpret these speeds? If you Google it you just get a lot of results dealing with how to improve your speed. We're not at that stage yet.

  • Fan speed monitor Software for Macbook Pro Unibody on Windows

    - by dtmunir
    I've tried multiple temperature monitor and fan speed software on my Macbook Pro Unibody under Windows 7 64-bit RC. None of them can report the fan speed. Currently I'm using SpeedFan which reports the CPU temperature of each of the two cores, but is not able to detect or interface with the Fans. Has anyone had any luck with this?

  • Maximum speed of data transmission

    - by JavaRocky
    All major data carriers these days use fiber optic links these days. And data transmission occurs at the speed of light, is that correct? If data transmission does indeed occur at the speed of light, is it also correct to assume that data transmission will never ever be faster?

  • Mac limit update download speed

    - by ILMV
    I have a Macbook with Snow Leopard that I need to update, but I want to limit the speed so it doesn't wipe out my entire bandwidth. Is there an application or setting change I can use to limit the speed to 20KBps? I've already tried ipfw through the terminal with little success. Thanks :-)

  • question about a sata read/write speed

    - by Joe
    I'm contemplating biting the bullet for an ssd drive in a server, obviously I know it will be MUCH faster than a regular 7200rpm sata2 3gbps drive. The nice thing about ssd's is often they post the read/write speed but that info isn't available for sata's so I'm just curious to know what a typical read/write speed would be for a seagate 120gb 7200rpm drive. I know it fluctuates from manufacturer and model series but I'm just looking for a guestimate.

  • Cut Caseload Costs, Speed Service Delivery For Social Services

    - by michael.seback
    Lower Caseload Costs, Speedier Service Delivery with New Oracle Social Services Solution Oracle has just introduced a new solution for social services agencies that's designed to help case workers address the challenges of rising workloads and growing demands by citizens for additional services. In the past, IT departments developed custom software in an effort to meet program outcomes. "Because this capability is out of the box with the Oracle solution, there's less complexity for organizations and an overall lower total cost of ownership," says Kimberly Ellison-Taylor, Oracle's executive director of health and human services. "Self service brings costs down to just pennies per interaction and makes it possible for clients to receive government services more quickly," Ellison-Taylor says. read more

  • VSTO is Free But Aspose is Speed

    - by Ken Cox [MVP]
    I’ve taken over the completion, deployment, and maintenance of an ASP.NET Web site that generates Office documents using VSTO. VSTO’s a decent concept and works fine for small-scale scenarios like a desktop app or small intranet. However, with multiple simultaneous requests via ASP.NET, we found the Web server performance suffered badly. To spread out the server’s workload, I implemented MSMQ task queuing via a WCF Windows service.  That helped a lot. IIS didn’t drag with only one VSTO/Office instance running. But I  still found it taking too long to produce a single report. A nicely formatted VSTO Excel document was taking 45 minutes.  (The client  didn’t know any better and therefore considered 45 minutes tolerable.) On my own time, I pulled out an old copy of Aspose.Total for .NET. Within an hour, I had converted the VSTO Excel C# code to Aspose Cells code. The improvement was astonishing: Instead of the 45-minutes, the report took under a minute! I’ve pasted the client’s exact chat response after he tried the speedy Aspose version: “WWWWWOOOOOOOOWWWWWWWW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!” Microsoft’s VSTO is a free product while the Aspose components cost $$$.  Certainly, it can be a tough call when budgets are tight. If you’re trying to convince the client to shell out for something more suitable for the application, get an eval version of Aspose.Total and offer a direct comparison demo. Ken Full Disclosure: Aspose (like several other component vendors) gives free copies of their suite to MVPs and other .NET influencers.

  • Speed, delta time and movement

    - by munchor
    player.vx = scroll_speed * dt /* Update positions */ player.x += player.vx player.y += player.vy I have a delta time in miliseconds, and I was wondering how I can use it properly. I tried the above, but that makes the player go fast when the computer is fast, and the player go slow when the computer is slow. The same thing happens with jumping. The player can jump really high when the computer is faster. This is sort of unfair, I think, because. Should I be doing this someway else? Thanks.

  • Improve speed of "start menu" in Linux Mint 10 - Ubuntu 10.10 derivative [closed]

    - by Gabriel L. Oliveira
    I have a global menu (including application, administration and system tabs) that is taking too much time (for me) to load (about 2.5 seconds). Of course, this time is taken only during first start. After it have loaded, next times are better ( less than 0.2 miliseconds) The menu was taking more time before (about 5 seconds), and I found that was because of the 'Other' part of the menu, that included many applications installed with Wine, so I removed all of them (I didn't need them at all). I have a "normal" knowledge of programming, and I think that the process of starting the menu for the first time has some kind of "cache function", that tries to find which apps are present that need to be placed under menu to be shown to user. But didn't found this function so that I could analyze in details what he is doing (if searching for files under "~/.local/share/applications" or anything else). Also, I found that hitting "Alt-F2" also fires this "cache function", because after waiting it to load, the process of opening the menu took less than 0.2 miliseconds. So, could anyone help me in order to reduce this time? I found on internet that some user could reduce the time by resizing the icons of applications. But found here that most of my icons are already at 25x25 size. Any other idead? Maybe a multiprocess to load it, or include it under startup... don't know. Ps: Sorry if this is an awkward question, but I just do not like waiting for things to happen, and think that this process should be smoother than it's now. Also, thanks in advance!

  • Improving the speed of writing code in C#

    - by Robert Harvey
    Laugh if you want, but I used to develop substantial line-of-business applications in VB6, long before the .NET framework came along. Why, when I was your age, we used to walk two miles in the snow, uphill. Both ways... Love it or hate it, VB6 had a REPL-like feel, and a very rapid development cycle. I would like to know how to come closer to that process in C#. In VB6, I could write a function, execute it, debug it and have it fully functional in a few minutes. I am told this is how the Lisp crowd works. It's a very rapid-fire style of programming. In C# I write a function, then I write a unit test for that function (which is OK, I understand the value of that), then I right-click, run test, wait for the project to compile (takes about 10 seconds right now, which would be an eternity for a REPL loop), and get an exception. Honestly, this feels more like my junior college days, when I used to feed punch cards into a hopper and wait for a printout (exaggerating only slightly for effect). Additionally, my tendency nowadays is to make everything public while I'm testing it. Unit testing with private accessors works fine, but you can't trace through the code (unless, of course, I'm doing something wrong) while you're using them. So what I'd like to know is, what adjustments have you made to your development process in C# to streamline it, and make it possible to write and verify your code very rapidly?
