What are the benchmarks like under FreeBSD?

Yes, mee too.

Is this really the question? Or is it first: Are we going to switch to
FreeBSD CAM stuff? If this has been decided by core/whoever is
for this decision, it's more likely that people step up to say, hey
if you guys want CAM in NetBSD, I'm glad to invest some time to port
it. Justin has already offered to support anyone trying to do so, but
to me it hasn't been clear that core wants CAM (Sounds like a good
to me, but then again, I haven't had a close look at it).

So, to make a long story short:

Do we want CAM in NetBSD???

Not me, but why has the machine on 64 MB RAM. This looks like it might
become a bottleneck sooner than hd-preformance :-)
