I found that rtorrent eats a lot of IO resourses when calculating hash, and I can't ajust that by making its nice higher. Even on +19 it is blocker Thanks There is ionice. It is part of sys-process/schedutils which is in portage. There is a manpage here http://linux.die.net/man/1/ionice as it is not included in schedutils. You can also take alook at http://forums.gentoo.org/viewtopic-t-462230.html. It is a forum thread about ionice. Just for your information: Ionice is also part of the util-linux-ng-2.13 the replacement for util-linux which is in portage but currently without keywords. The stable version 2.12r-r7 is the old util linux where ionice is not included. So you have to use 2.13_rc2 which is util-linux-ng but there is always a reason why there are no keywords!

Re: [gentoo-user] IO scheduling
I forgot to mention that I think you need to be using the CFQ scheduler. Change ionice class doesn't seem to affect the deadline and anticipatory schedulers' behaviour. Also I think I had an extra space in there after the -p. Try: ionice -c2 -p`pidof rtorrent` -- [EMAIL PROTECTED] mailing list
