I've also had (and still having) this problem on FreeBSD 7.2-RELEASE and 8-STABLE with both UFS and ZFS. Though, i've been running FreeBSD not on powerful servers, but on laptops (2-core CPU's, 2 GB of RAM). But still, KDE4 on Linux performs much better during high disk IO. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
