- If "w" and "top" does NOT show real CPU load, then
how to check real CPU load?
- How to check which process cause high load on "w"
and "top"?
Thanks.
In your case, you have 2 Zombie processes ... and one running process. Since those == 3 ... I would suspect that they are driving your load up ... although that might not be the case.
This will tell you how to find Zombies:

I would start there.

Recently we installed CENTOS 4.4 on DELL 2650

We found CPU load always on 3 and up if we run
"top"
or "w" to check. There is NO application run on
this
server why CPU load so heavy?
Load showed by top and w isn't cpu usage. The load average is the sum of the run queue length and the number of jobs currently running on the CPUs. If you have a process waiting to access the disk for something, you can drive your load average pretty high, while using virtually no cpu.
