Probably the best references are the following manual pages + source code: dsched(4), dsched(9), dsched_bfq(4) Main kernel files are in 'sys/kern/dsched'. There is a good post on the bfq scheduler here: http://leaf.dragonflybsd.org/mailarchive/kernel/2011-08/msg00008.html There is also a 'fq' scheduler, but it does not have a manual page. A good intro 'project' to get up to speed would maybe be to review this scheduler and write a manual page documenting it - there were also some kernel posts to dig up from when it was being added as well. Speaking of - survey time! Who's using I/O schedulers currently & with what settings?? I had turned off my fq config at some time previously in a failed/misguided attempt to isolate some stability problems and haven't got back around to reconfiguring.. Cheers, - Chris
