Thanks again. I don't think the I/O bandwidth is issue. Because once I run the parallel with all time the run happening I am seeing the CPU usage as as 99% . So if that is an issue with I/O then the all process wont run at 99% right ?

When I forked out different process. Each will have the same priority right and I/O is the shared resource which should be equal to all process. that's what I am confussed

I am using top to determine the speed. is there is any utility which give more insights ?
