C# High Cpu Usage

I'd also add that if you need maximum performance, you can use a statistical trick to avoid sleeping when sensor data has been read. When you examine dump files that you've captured during a time of high CPU utilization, you can fairly easily see which process or processes are using all the processor time. On a Windows 2000 server, right-click the appropriate log listed in Performance Monitor under Counter Logs, then select Stop Log. Note that if you see a thread that's using a lot of CPU time but that dies down to 0 percent for several seconds at the end of the log, you

As mentioned, when software goes live, things could go wrong, and code could start executing in a way we didn’t plan. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization. where does the data you wait come from? The logic layer subscribes to the ReadForwardevent that is exposed by the Reader Layer and forwards that data to the relevant logic block by writing to its ConcurrentQueue.

At what point is brevity no longer a virtue? Create a timer that fires every 200 ms, and have it do the work. So I'm open for suggestions. –Coach Roebuck Nov 18 '10 at 22:41 I think I may turn around and use a Windows Task Scheduler instead instead of trying to http://stackoverflow.com/questions/4219708/cpu-usage-becomes-very-high-during-execution Detect ASCII-art windows made of M and S characters How to bevel only one end of a cylinder?

Why do CDs and DVDs fill up from the centre outwards? Thanks for the useful article, Juan! that doesn't cost any cpu. I suspect it has something to do with placing it in a for next loop.

How 'bout now? Have you tried adding a pause to your thread execution between loops? The final dump will be a dump with full memory, and that dumps will be much larger. http://supportcanonprinter.com/high-cpu/opera-high-cpu-usage-fix.html Click Next again.

Probably you may have to sleep the thread accordingly. –CharithJ May 20 '11 at 0:14 add a comment| 5 Answers 5 active oldest votes up vote 11 down vote accepted while share|improve this answer answered Nov 18 '10 at 21:31 Steve Townsend 42.6k457112 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google If IIS is causing the problem, the offending process will be inetinfo.exe or the out-of-process (OOP) executable dllhost.exe (Windows 2000) or mtx.exe (Windows NT 4.0).

Later, out of curiosity, I built a very small program, in which all it does is start a small thread, or timer, then runs some incredibly long loop. share|improve this answer edited May 20 '11 at 0:29 answered May 20 '11 at 0:12 Alex Aza 45.5k15117115 Hi. The PC basically locked up because so much of the CPU was used for maintaing threads (maintaining them, not executing them). Go to the desired thread by typing ~s (e.g., ~7s).
