Perl script limit cpu usage
Hi Experts,

I am executing multiple instances(in parallel) of perl script on HP-UX box.

OS is allocating substantial amount of CPU to these perl processes,resulting higher cpu utilization.

Glance always shows perl processes are occupying majority of the CPU resource. It is causing slower response time for other processes as majority of the cpu resource is always occupied by perl processes.

Is there any way to limit the amount of cpu used by perl processes?

Thanks in Advance for your help!!
