But i can see many of them are in sleep state. Is it possible to run all the commands like changing the priority.As its taking much time in the output.

Regards

How do you start these commands? (There are several meaning of words "to run parallel").

How many processors do you have? How many cores each? Is Hyper-Threading or anything similar active? Because, basically, the output from top and others is a moments snapshot, and it's only possible to have at most 1 process running per processor core at any time, with the others sleeping until it's their turn.

I started all the commands from a shell script using while loop & send all the commands to backgroud.

Are the processes starved from disk I/O? I.e. is your disk seeking all the time?

If you want more control over your processes in parallel consider using GNU Parallel to start similar processes in parallel.
