Same trouble
Hi ,
I am facing a similar problem on the same configuration.
In my case the problem is the cpu usage does show 97 - 99 % usage and also there is no i/o wait, when i fire multiple processes.
but i don't get the performance.

Basically i m running a application which generates small files.I need to generate around 170 files per minute. If run just one process one file takes 5 secs to generate. When i run say 10 process it shows 40 secs to 200 secs for certain files and also the average time is around 4 secs per file.

Is it that i m overrunning the process or do i need to set some kernel parameters.Please help.
