i've just tried the 10,000 fork test on a Sparc Classic
unix
156.1 real 136.9 sys 13.5 user dynamically linked
58.7 real 50.4 sys 3.2 user statically linked, dynamically paged executable
58.8 real 51.1 sys 2.8 user statically linked, not dynamically paged image (-n)
plan 9
26.9 real 20.4 sys 0.8 user no need to choose
the sparc classic has tiny caches, and a sleazy implementation of the Reference MMU
(TLB context flushes are implemented as complete TLB flushes). i might revise the MMU code,
but i don't think it will help this test on this model of sparc. memmove might
be made faster, though; i haven't checked yet. i haven't got figures for the ss/10,
since that hardware is different again.

just a little more evidence that suns suck.
when the 670mps came out, i remember doing a fork test
on a vax 11/780 running xinu and the sun running sunos4.1.xx.
the sun as i remember was about 10x as slow as the vax,
and it was even slower if the child process touched memory.
and the 11/780 is a 1 mip machine.
