I hear everyone talking about how multi-threading can improve performance. I don't believe this, unless there is something I'm missing. If I have an array of 100 elements and traversing it takes 6 ...

Are they just figured out using the same mechanism as a linear search or is the range narrowed down somehow, similar to a binary search.

I'm looking for some kind of a library that gives me accurate CPU frequency values periodically on both Intel and AMD processors, on 32-bit and 64-bit Windows. The purpose of this is to accuratly ...

If Moore's Law holds true, and CPUs/GPUs become increasingly fast, will software (and, by association, you software developers) still push the boundaries to the extent that you still need to optimi...

The Trick is I also need to be able to do it on multicore machines. My education in C# is a tad broken. I have managed the following code. Can anyone help me out? I have tried using the "_Tota...

Which is better in terms of CPU optimization for a web server? Writing plain HTML and inserting PHP code here and there? <script type="text/javascript">$(document).ready(function(){$('#searc...

I have an application in which I am sending network data over WiFI. Everything is fine until I turn the display off or the device goes to 'sleep'. I'm already locking the WiFi however, it seems to ...

Edit: My original example had a silly mistake. After fixing it I still get weird results, though. In my naive attempt to measure my CPU speed the "brute-force" way, I made the program below: #i...

I want to stress-test my application this way, because it seems to be failing in some very old client machines. At first I read a bit about QEmu and thought about hardware emulation, but it seems ...

I've written a game for Android, and I've tested it on the Dev Phone 1. It works perfectly, the speed is just right. However, I'm sure phone CPU's are getting faster. They may already be faster tha...

I know this is a micro-optimization, so I ask out of pure curiosity. Logically, a microprocessor does not need to compare all the bits of both operands of an equality operator in order to determi...
