So I've noticed that linux seems to be able to fudge a heck of a lot
of disk io performance from just throwing huge amounts of cache at the
problem.  Although inelegant, this approach really does seem to move
disk io right along.  I'm wondering if the same effect can be duplicated
in NetBSD, or if NetBSD has an even better approach to the problem.

Currently linux does have measurably better filesystem performance than
NetBSD (even when fses are mounted asynch/noatime) at least according
to hbench (I measured NetBSD 1.4.2 against linux 2.2.14), so this is
more than idle curiosity.
