It has been *really* slower to load many files (modules) since I
switched to ZFS on root. I had to build a monolithic kernel to save
10-15s of loading time.

Now I use trasz@'s (CC'ed) patch to speed up the loader, and it seems
maybe as fast as with UFS. I don't know if the patch speeds up things
with UFS, but with ZFS it made a big difference.
