Hi,
I ran a mildly memory intensive integer benchmark (Ford/Fulkerson
network flow optimization) on a PC164, and it took 50.3s with
NetBSD-1.3.3 and 48.4s with DU4.0E, same assembler source, but assembled
and linked on each target OS.

I'll try it again with 1.4 to see if it's a problem of the old VM, or if
the DU binary is faster with the emulation, or maybe it's something
completely different.

On a PWS433au with 2MB cache (and Dec Unix) it took only 48.1s, so I
already wonder whether it was a good idea to buy a board with only
1MB cache :-)
I use the PC164 with 256bit memory mode.  Is the main memory of a PWS
much better than that or is the PC164 likely to be constrained by the
L3 cache size in this case?
