I have a process doing some heavy calculations (par2) on an encrypted partition. The process is running with a nice value of 10, but kcryptd, which I suppose is a kernel module handling the encryption, is running at priority "-5", and sometimes it uses far more cpu - which means that the rest of my user processes are running with lower factual priority than the "background" par2 process. A similar situation occurs when I copy several gigabytes to an encrypted partition: even if the copy runs as "nice", the background kcryptd runs at higher priority than normal, slowing the entire machine.
As kcryptd is not a child process of par2, it does not inherit its niceness value, I understand - but it is a real nuisance.
Can this situation be changed?
Have you tried renicing kcryptd? I googled and saw one or two mailing list posting where people had reniced kcryptd to 0. -- Per Jessen, Zürich (10.8°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
