As said, the environment was a bit different. I'll recheck this in the same
environment (hoping, the DELQA isn't much different in throughput than the
LANCE of the VAXstation). I don't think of a disabled cache, this would have
been much more difference between the both boxes.

The 4000/300 is at 8 VUPs, while the VS 3100m76 is at 7,6 VUPs. CPU is exactly
the same, so i think, the speed difference may result from different caches and
maybe even the different system bus.

I'll send better results when compiling in exactly the same environment:
completely netbooted and networked root.
not that loaded nfs-server i had this time. (MP3-encoding eats much CPU power).

so long.. Michael
