As keeper of the 'stones results in the USA (reminding me its high
time to post the latest summary*), I couldn't help but notice that
the results you achieved for the 386 boxes are way out of line.
Unless those machines are severely crippled, your results are off
by at least a factor of two.  I'm not familiar enough with the 486 to
comment on that result.  My guess is that the benchmark was compiled with
HZ=60 rather than the correct value of HZ=100.  16 Mhz plus cache 386's
turn in around 5K stones, 25 and 33 Mhz plus cache in the 7K to 12K range.

* BTW, I find that I have no results for 486 in my mailbox.
Could someone with access to a 486 and UNIX volunteer to send
some results to pcrat!dry2?
