If you're using UFS, I've found it to be quite a bottleneck when doing parallel IO: I even ran a "svn up" in one terminal and tried to login on another a couple of days ago only to find the motd took over 5 seconds to appear! That may be excessive since I was running a kernel with WITNESS and INVARIANTS, but I've found ZFS to be far better if you want good interactivity when reading/writing to disks. -- Bruce Cran _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
