NetBSD speed curiosities

[John Klos <john%ziaspace.com@localhost>]

Hi,

I'm still puzzled by one thing that perhaps someone could explain. The 
Dhrystone benchmark from pkgsrc should be pretty consistent due to its 
simplicity. However, my 4000/30 (VLC) with NetBSD 6, which by many sources 
is supposed to be 5 VUPs or so, only reports 2109 runs per second, which 
is only about 1.2 times faster than the runs per second of an 11/780.

A 4000/60, which is supposed to be about 12 VUPs, gives 16305 runs/sec, 
which is about 9.2 times faster than an 11/780.

Why is this? Is there some issue which makes code too large to run inside 
of the CVAX SOC's 6k of cache? Is anyone running NetBSD 1.5 or another old 
version who could get some more numbers?
