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.

System calls happen *much* faster on linux.

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