There was an article about a kernel patch to improve performance.

it involves adding this to ~/.bashrc

|   if [ "$PS1" ] ; then  
           mkdir -m 0700 /sys/fs/cgroup/cpu/user/$$
           echo $$ > /sys/fs/cgroup/cpu/user/$$/tasks

and  this as root:
||mount -t cgroup cgroup /sys/fs/cgroup/cpu -o cpu
mkdir -m 0777 /sys/fs/cgroup/cpu/user|

My machine Centos 5.5 does not have a /sys/fs/cgroup

Is there anything else to do instead?
