Hi Jan, Thanks. I like when people can separate their opinions from facts.
I'm gonna try out linux some more. I already have a dual boot system. I just have to port some of the fixes I've made to OSG so that I've got the same baseline. One of the things that really degraded performance was DOFTransforms. I'll port that change and see what I get. I have a commercial image generator that does paging very well on windows, so I know it is possible. However, I did notice it uses a real-time extension, and many many more threads. Watch out linux; I'm about to give you a thorough examination.

Also, Linux usually doesn't block the rest of the system while doing I/O as Windows likes to do when under heavy load. However, as I said at the start - these are my impressions not benchmarks. If you want to be sure, set up either a dual boot or one of the live distros which boot from the CD, put your data and application on the harddrive and benchmark it. That is the only way how to be sure.
