There are many factors affecting performance (and ways to measure them).
NetBSD/sun3 does fairly well on CPU-intensive work (i.e. Xsun) mostly
because we have a better compiler (gcc) than the SunOS 4.1.1 compiler.

On the other hand, the current SCSI driver does not make any attempt
to be fast, so disk performance is atrocious.  There is a better SCSI
driver in the works, but it's not quite ready for "prime time"...

Hmmm... Haven't seen that.  Is everything up-to-date?
