[wlug] performance difference between a swap partition vs a swap file >>>>>

I have done a lot of research, but I do not have any real world experience so I'm hoping you can help me understand the real world differences in performance. The research tells me that if you create a swap file on an empty disk and on a OS using kernel 2.6 then the performance differences are minor, but that the swap partition is a slight favorite in terms of pure performance. Our Scenario: Raid 1 146GB partition 33GB Swap File created on / (Note: the swap file was created when the OS was built, so the hard drives were not full and they were very empty) Kernel 2.6 Best Regards N
