system resource

[addendum]

I found that in my system , there is a strange process that its process name is "osw" , if this process is running in the system , the system will become very slow ( because it will use much CPU time ), so I want to control this kind of process ( eg. if the process command is "osw" ) can only use maximum of a certain of CPU resource ( eg. 10 % ) , is it possible ? thx

You can change the cpu prioirty with nice utility so that it can not run by using more resource. check nice man page.

hth.

thx reply ,

if not only want to set the prioirty , I want to control the cpu usage by process name , is it possible ? thx

no, it isn't possible set maximum cpu usage. setting the lowest priority ensures that process uses very low cpu when other processes need it. But it will get 100% cpu when there aren't other processes running.

# renice 19

or

# renice 19 $(pgrep osw)


Ciao!

I think that nice or renice will do the job, anyway, there is a kernel patch, but I think that is not updated:
