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. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.11.0-12-generic.
