try lmbench, as well.

i woudlnt mind checking it out.. ill run my personal 'benchmark' , just a
number sieve.. but its my own bogus metric of machine speed :) 

btw i will probably be the proud owner of a VAX 4000/600 soon, just making
shipping arrangements for it now.. it's not supported yet, is it? if not,
does anybody have any docs? i dont think it woudl be very different from 
the vax4400 or 4500.. 

btw it turns out that i was mistaken about the speed of the pcc-generated 
code- it was in line with what ragge's post said, i had done my stuff on 
a ka650 and had miscalculated the speed ration from the 8600 to the 3600 
and gotten delusions of grandeur and speed from it.. :) 

happy hacking,
