[Devel] cgroups and limit firefox processes cpu time

[william]

Hello list

I have a question about how i can limit the cpu for a firefox process on 
a terminal server.

We have 150 firefox processes running on a terminalserver but there are 
always people who take more cpu when they use flash or java.
Some firefox processes take sometimes about 50 percent cpu time.
Is there a way to give all firefox processes equal cpu shares so that 
other people who are using firefox for research have no issues (slow 
responding scrolling and menu)  because there are a few firefox 
processes eating all the cpu time?

I hope i made clear what i meant, this is new to me and i haven't found 
other people with examples doing the same.

e.g
1 core
firefox 1 80%
firefox 2 60%
firefox 3 10%

now what i want is that the firefox processes 1 and 2 get the cpu time 
they want but if firefox process 3 is going todo something then he gets 
the cpu time he want's because the first two are over there limit.

I will be happy to answer questions to make this more clear.

With kind regards

William
