Hi,
I'm trying to use cgroups to limit the apache webserver but this doesn't
seem to work as far as I can tell.
I modified cgconfig.conf like this:
group webserver {
cpu {
cpu.shares="250";
}
}
and addes this to cgrules.conf:
*:httpd * webserver
Looking into the "webserver" cgroup shows that the pid's of the httpd
processes are correctly assigned:
$ cat /cgroup/cpu/webserver/tasks
6191
6193
6194
6195
6196
6197
6207
Yet when I run a php file with a dummy loop I get a process with 100%
cpu usage until the script times out which is not what I expect.
Am I doing something wrong or why doesn't the cpu.shares setting seem to
take?
Regards,
Dennis
