I'll sure vote for all of the above!  I'll even second the motion.

SunOS-4.1.1 on the sun3 is slow, but NetBSD (~9604) is really slow,
where it truely could, and should, be faster.

I have been trying to do some user-land benchmarking between SunOS and
NetBSD on identical platforms (both in production environments,
unfortunately), but I've no conclusive results to clearly point in any
specific direction yet.  It seems the raw disk performance is OK on
NetBSD, which could point at the filesystem, but others have said it's
really the buffer cache and the VM that might be at fault.

I still need to run lmbench though....
