CPU usage always below 10% in windows server 2008 r2 x64
- by ???
I am using a server with windows server 2008 r2 running on it to run my program. The CPU of the server is Intel xeon x5570 2.93GHz with 2 processors, 8 cores per processer.
However, I found that the cpu usage is almost always below 10% even I use 32 threads in my program. And I also found that sometimes the cpu usage could reach as high as 93% through the task manager when running my program and at that moment my program has processed over 1000 files per second while normally, it only processed over 50 files per second. However, this does not happen often.
I use tools downloaded from the internet to make sure no core sleeps when the server is on, nothing changed. Also, I edited the windows register to make sure that I, as an administer, have no cpu usage limit. But it changed nothing.
Is there anyway that I can make full use of my cpu? That is to say that each core runs a thread of my program and the total cpu usage could reach over 50% when I use a reasonable number of threads in my program.
Did this happen to anyone of you? And could you help me with this ?
Thank you!
