restricting Max CPU Utilization per process
 

is there any way i can restrict the maximum cpu utilization of a process as reported by top(%CPU). ulimit does not seem to do that . The process is running continously and peak utilizations reaches 80% . Normally when the process does not recieve any traffic it's utilization is near 0. Is there any way i can start this process or set a kernel parameter such that it's cpu utilization never increases 20%( or some predefined soft limit)
Thanks

Try this program:
