u can limit the CPU utilizatation of a process by settin nice value

for example

nice -15 command

by default it is 20

if u want to make ur process less prior means

reduce the nice value

nice -10 command
it wil run the process at nice value 10(20-10)

if u want to make the process more prior means u have to increase the nice value
but only root user can increase nice value

# nice --15 command

this will run the process at nice value 35(20+15)

refer man page for nice command.

If it was HP-UX I would have suggested to use PRM .

But Don know how to do that in Linux
