I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.
As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:
group browsers {
cpu {
# Set the relative share of CPU resources equal to 25%
cpu.shares = "256";
}
I hereby claim:
To claim this, I am signing this object:
