I have heard very dire warnings about disabling the ZIL, especially when using NFS (as I am) http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#ZIL So unless this doesn't affect FreeBSD, I'm not inclined to disable the ZIL. I'll try disabling prefetch, though. Thanks for the idea. I'm still interested in trying out the patches, though, if anyone has gotten them to work recently...
