** Description changed: - I'm using Ubuntu 11.10 dev. I'm starting apache with the command "chrt - -i 0 ionice -c 3 /usr/sbin/apache2ctl". On my system is full data - journaling enabled. Theoretically if apache or a child process from - apache is writing something to the disk it shouldn't affect any other - applications like games because apache has the lowest cpu and I/O - priority possible. But sometimes a child process from apache is writing - a lot to my disk and I can't do much at this time anymore. If I play a - game it is freezing every second and unplayable. If I disable full data - journaling it is much better. This is why I think the [jdb2/sda1-8] - process doesn't inherit the nice/ionice from the writing process. + I'm using Ubuntu 11.10 dev.
