Hi Peter,

You are right about the memory being faster and that is a direct factor in 
what I am doing. But still I cannot explain a factor of 2 in speed other than 
the fact the Linux OS handles resources much better than Windows.


Vista Hardware:
Dual-Core Intel? Xeon? Processor 5160 3.00 GHz 1333 MHz FSB 4 MB L2 
cache EX615AV 
Dual-Core Intel? Xeon? Processor 5160 3.00 GHz 1333 MHz FSB 4 MB L2 
cache (2nd) EX616AV 
HP 8GB (4x2GB) DDR2-667 ECC FBD RK355AV 
HP 250GB SATA 3Gb/s NCQ 7200 (1st) EM060AV 

Linux Hardware:
2.33 GHz Intel Core Duo
8 GB DDR2-8 MHz RAM
Hard disk same speed as well as capacity.
Thanks.

Suresh
