Thanks!

Those are as good, if not better, 
than the bogus byte bench results :)

Seems you see some 3% to 4% improved 
user/system time (this is a 486DX2/66,
I assume ... ?)

DX2/66	22902.31 real     17493.97 user      3495.63 sys
AMD5x86	16795.20 real     11689.23 user      2822.52 sys	*1.50 (user)
P133	13449.10 real      8789.22 user      2073.65 sys	*1.33 (user)

Since I just went from a 486DX2/66 to
an AMD 5x86, I thought I might just 
post my make world result, and have 
added a 2.1R make world posted by JKH
a few weeks ago ...

Seems that an AMD 5x86 is more than 
halfway towards a P133 :) :)
