Serious zfs slowdown when mixed with another file system (ufs/msdosfs/etc.).

[Freddie Cash]

Search the archives for the -stable, -current, and -fs mailing lists
from the past 3 months.  There are patches floating around to fix
this.  The ZFS code that monitors memory pressure currently only
monitors the "free" amount, and completely ignores the "inact" and
other "not actually in use" amounts.
