Hi,

I wanted to get the experience of other people regarding the
performance of 64-bit OS's vista and Fedora Core.

I have a quad-core hp workstation running 64-bit Vista (8 GB
RAM) and I have Linux Fedora Core 8 (64-bit) on a dual core
regular hp desktop with 8 GB RAM.

I am running matlab analysis of very memory intensive and
also  involving lot of disk reading to perform calculations
on about 3000 images. I am using the exact same code on both
platforms.

To my surprise, I get 2x better performance on the above
linux OS as compared to the above vista. The time I am
talking about is, 3100 sec (vista) vs 1700 sec (linux) for
the calculations.

I would like to know about the experience of other people. I
am almost tempted to ditch vista and install 64-bit linux on
 the quad-core hardware.

PS: I have enabled multiple threading in matlab for both
cases. So basically the conditions are exactly identical.

Thanks.

Suresh
