4 CPU Dell 6650 - 2.0 GHZ
3 GIG RAM
Not much happening on the box:

C:\temp> t.pl
Time: 8 wallclock secs ( 7.78 usr + 0.00 sys = 6.00 CPU)

2 CPU Dell 2250 ( I think that is the correct model) - 1.0 GHZ
2 GIG RAM
Not a lot happening on this box either.

17:57-rsysdevdb:dv03:jkstill-14 > perl t.pl
Time: 6 wallclock secs ( 5.76 usr + 0.24 sys = 6.00 CPU)
[ /home/jkstill/tmp ]

System calls happen *much* faster on linux.

When tested on like hardware, Linux is ~ 100% faster.
