I'm working on a project which uses .NET Remoting for communication between the client application and an object server. For development, the client, server, and MSSQL database are all running on my local development machine. When I'm working at the office, the responsiveness is just fine. However, when I work from home the speed is ...
I have an Ajax.Net enabled ASP.Net 2.0 web site. Hosting for both the site and the database are out of my control as is the database's schema. In testing on hardware I do control the site performs well however on the client's hardware, there are noticeable delays when reloading or changing pages. What I would like to do is make my appl...
(assume php5) consider <?php $foo = 'some words'; //case 1 print "these are $foo"; //case 2 print "these are {$foo}"; //case 3 print 'these are ' . $foo; Is there much of a difference between 1 and 2? If not, what about between 1/2 and 3? ...
Any ideas what the average user's download speed is? I'm working on a site that streams video and am trying to figure out what an average download speed as to determine quality. I know i might be comparing apples with oranges but I'm just looking for something to get a basis for where to start. ...
I am trying to achieve better performance for my Java SWT application, and I just found out it is possible to use OpenGL in SWT. It seems there are more than one Java binding for OpenGL. Which one do you prefer? Note that I have never used OpenGL before, and that the application needs to work on Windows, Linux and Mac OS X. ...
I have recently been befuddled with comments regarding the speed at which some people claim to be able to develop various applications. I tend to feel that there is a definite relationship between application quality, reliability and speed of delivery. I take Stackoverflow as a good example. I love the quality of the site, (and I think ...
Does anyone know how the speed of pylons(or any of the other frameworks) compares to a similar website made with php? I know that serving a python base webpage via cgi is slower than php because of its long start up every time. I enjoy using pylons and I would still use it if it was slower than php. But if pylons was faster than php, I...
Suppose I have a collection (be it an array, generic List, or whatever is the fastest solution to this problem) of a certain class, let's call it ClassFoo: class ClassFoo { public string word; public float score; //... etc ... } Assume there's going to be like 50.000 items in the collection, all in memory. Now I want to obtain as f...
I have a simple .NET 2.0 windows form app that runs off of a networked drive (e.g. \MyServer\MyShare\app.exe). It's very basic, and only loads the bare minimum .NET libraries. However, it still takes ~6-10 seconds to load. People think something must be wrong that app so small takes so long to load. Are there any suggestions for impr...
I need to keep as much as I can of large file in the operating system block cache even though it's bigger than I can fit in ram, and I'm continously reading another very very large file. ATM I'll remove large chunk of large important file from system cache when I stream read form another file. ...
I have a lot of nice MATLAB code that runs too slowly and would be a pain to write over in C. The MATLAB compiler for C does not seem to help much, if at all. Should it be speeding execution up more? Am I screwed? ...
I'm looking for some metrics. I'm currently tech-editing a book in which the author boldly states that "ASP executes faster than CGI and Perl". It's not backed up by any sources or anything that would lead me to believe that was a fact, so I'm wondering, does anyone know the answer to this question? I've done some google searches, but ha...
I'm using a local artifactory to proxy the request, but the build and test phases are still a bit slow. It's not the actual compile and tests that are slow, it's the "warmup" of the maven2 framework. Any ideas? ...
For intense number-crunching i'm considering using fixed point instead of floating point. Of course it'll matter how many bytes the fixed point type is in size, on what CPU it'll be running on, if i can use (for Intel) the MMX or SSE or whatever new things come up... I'm wondering if these days when floating point runs faster than ever...
This is really two questions, but they are so similar, and to keep it simple, I figured I'd just roll them together: Firstly: Given an established python project, what are some decent ways to speed it up beyond just plain in-code optimization? Secondly: When writing a program from scratch in python, what are some good ways to greatly ...
If you have the following: $var = 3; // we'll say it's set to 3 for this example if ($var == 4) { // do something } else if ($var == 5) { // do something } else if ($var == 2) { // do something } else if ($var == 3) { // do something } else { // do something } If say 80% of the time $var is 3, do you worry about th...

Several people round here recommended switching to the new WD Velociraptor 10000rpm harddisk. Also magazine articles praise the performance. I bought one and mirrored my old system to it. The resulting increase in compilation-speed is somewhat disappointing: On my old Samsung drive (SATA, 7200), the compilation time was 16:02. On the ...
