--nextPart1317096.xfUj6sXRYQ Content-Type: Text/Plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I've used geom_sched to some success. Normally I do not notice anything bu= t=20 today I was copying big files over a gigabit ethernet and my laptop was not= =20 very responsive. I loaded gsched and the responsiveness improved (although= =20 still rather bad for anything requiring something from the HDD). =20 Thank you for all this work :-) Some questions I have: - with a gmirror should the gsched be attached to the underlying devices (= aka=20 /dev/ad?) or to the mirror device (aka /dev/mirror/?)? - is there anyway to automatically attach gsched to a device on startup (i= =2Ee.=20 in rc.conf)? - is there a way to prioritise random IO (vs sequential reads from big=20 files)? - gsched_as does not appear to be installed. =20 Regards, David --nextPart1317096.xfUj6sXRYQ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (FreeBSD) iEYEABECAAYFAky7+qgACgkQUaaFgP9pFrL59wCfaj2C5mVkmjEO0Auagkk0vJUq iiQAoId1UUgE38k8pLqBwGfLzjEpTNKs =69dE -----END PGP SIGNATURE----- --nextPart1317096.xfUj6sXRYQ--
