[-- Attachment #1 --] Hi, I've used geom_sched to some success. Normally I do not notice anything but today I was copying big files over a gigabit ethernet and my laptop was not very responsive. I loaded gsched and the responsiveness improved (although still rather bad for anything requiring something from the HDD). Thank you for all this work :-) Some questions I have: - with a gmirror should the gsched be attached to the underlying devices (aka /dev/ad?) or to the mirror device (aka /dev/mirror/?)? - is there anyway to automatically attach gsched to a device on startup (i.e. in rc.conf)? - is there a way to prioritise random IO (vs sequential reads from big files)? - gsched_as does not appear to be installed.
