Hi,

I wonder how you measured CPU load ?
 

If your processes have short message queues, then that is good news at least.  I would suggest looking at your etop output to see where most reductions are spent.
 Then if that does not help, fprof will get you very detailed information.


 Good luck
Philip

 Our Project just get in some trouble....
The CPU Load seems too high (10 for 8 core CPU).
we use etop and find out that no any process has more than 1 message.
 Now I don't know how to investigate next.
Could some one give me some advice?
