After being up for a few days and having good performance, I turned on rTorrent and downloaded two 700MB files. After these torrents completed, my performance has tanked again. My combined read/write speed to the array won't exceed about 25MB/s.
It seems that after having downloaded a few torrents, resources are grabbed and then not released. From top: Mem: 2326M Active, 962M Inact, 484M Wired, 82M Cache, 418M Buf, 87M Free Nothing in userland is using a significant amount of memory. eg rTorrent is using 41MB according to top. Killing rTorrent does not alleviate the performance problems. arcstats.size is hovering around 30-40MB.

(I don't want to do it yet in case someone wants a specific number before I do that). _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
