Can I set a maximum percentage of CPU resources a specific program or process can use? I want to use the executable name instead of its pid, because I would like certain executables to always run with constrained resources. The reason I ask for that is that I am bored of the way Shockwave Flash behaves. It is not possible that to draw a...
I hope this is the right place to ask this question, as I think it is related to algorithms and performance. On my desktop, I have a little widget that tells me my current CPU usage. It also shows the usage for each of my two cores. I always wondered, how does the CPU calculate how much of its processing power is being used? Also, if ...
When I ran this code using gcc, $ cat eatup.c #include<stdio.h> #include<stdlib.h> int main() { int i = 0; while(1) { i++; } } $ the CPU graph went like this : I am not sure why there is a cross in the CPU core usage. I started the run at the rise to the left of the 40 mark, then initially core2 usage rose to...
I'm writing a unit test with Boost.Unit, and the code I'm testing must not exceed 50% of a single CPU during a portion of the unit test. How could I make this assertion from within the source code? ...
I have some scripts that use a ton of cpu is it possible to cap the amount of cpu a process is allowed to use? I am running on CentOs 5.5 by the way. ...
Hi. I have a basic question. If I run an executable file (Release, Visual Studio 2010) on two computers with the same CPU speed run two different Windows operating systems, eg. Windws7 vs XP, shall I expect to see different CPU usages when I measure it using the task manager? Is the CPU speed the only factor to measuring the CPU usage?...
I have an Apache2 + mod_python setup which has begun responding impossibly slow since some days - two seconds of processor time for any request of my app. Some interesting points: Debugbar says it's ~15ms of query time. DB is not the main suspect Logging with datetime.now() shows 0.1s is spent inside the view, and 40ms more are spent i...
I am using the following code to profile my operations to optimize on cpu cycles taken in my functions. static __inline__ unsigned long GetCC(void) { unsigned a, d; asm volatile("rdtsc" : "=a" (a), "=d" (d)); return ((unsigned long)a) | (((unsigned long)d) << 32); } I don't think it is the best since even two consecutive call...
Can anyone speak to how the different browsers handle the following: Picture an HTML document essentially rendering content of a static app with lots of data. <div class="abundant_class"> <div class="abundant_class"> <div class="abundant_class"></div> <div class="abundant_class"></div> ... </div> ...
I surf to a web page (the web page belong to my company...) and my explorer is stuck on 100% (desktop, windows XP, 1.5G, IE7, SP3) I'm not sure I have all the pdb and the information needed but the call stack from analyzed dmp file in dbg is below - does it look familiar msls31!InitGroupChunkExt+0x11a msls31!InitGroupChunkExt+0x25e ...
I am reading from a NetworkStream that is in a while loop. The issue is I am seeing 100% CPU usage. Is there any way to stop this from happening? Here is what I have so far: while (client != null && client.Connected) { NetworkStream stream = client.GetStream(); data = null; ...
How to get CPU and RAM usage for each process in C# using WMI ? I want to do something like windows Task Manager just simpler. Best regards. EDIT: OK, after some testing I found few isues: 1. Process class from System.Diagnostic has to many limitations when dealing with remote system 2. WMI to remote computer is very slow, about 15 s...
Though Its a n00bish question I'vent found any clear answer anywhere even after long days of googling. Recently I am Planning to Use a AMD Opteron Quad Core 2350 for my Home Lab. I'll not run it as a Pro Server. rather I'll use it for Development Only. It will have the following things 2 Instances of Apache Server (I'll Need this) 1...
In my Cpanel account in Daily Process Log I can see that my zend framework application load CPU very much Top Process %CPU 182 /usr/bin/php /home/*******/public_html/index.php But any requests to ZF application goes by index.php (with rewrite rule for Apache) Is it possible to find out what request (url) load CPU? ...
