I'd like to know if there is some way I could limit the processor usage of an application.
I mean, I have a cpu eat application but I'd like to give it just 30% of my processor. Is there some way I could do that?
I saw ulimit, but it limits the processor usage by time.
The most common way to address this is with the nice and renice commands.
Hmmmm, how I could use it? Nice is meant to let me adjust the process priority isn't it?
But my process is to be run, but not to run at 100% processor usage :)
The process I'm trying to use is zsnes, an snes emulator. I know emulation does take a lot of cpu, but as I have a piv 2.8, I think that 30% of this processor power is enough. I mean, I have a pentium 166 and zsnes runs with an acceptable performance. As I'm running Chrono Trigger game which is an rpg and so not so much graphics intensive.
So, the problem to me is not not get responsive system. zsnes is polite enough to even being at 100% usage, I didn't notice any hung of my system while using it. In fact, I can see other programs hanging it :)
I just don't want to use all the processor power to allow better battery usage and mainly keep my processor temp as low as possible. I mean, I didn't want to keep my cpu running at 100% for one, two hours in a row. Without sleep.
I hope it helps clarify what my problem is.
Thanks in advance.
