I have a doubt a little old: the position of the pagefile (swap) in the partition influence on the system performance? in the C: drive (about 11GB the swap was in the beginning of the partition) after an offline defrag with O&O defrag (last version) the swap was moved to the middle-end of the partition, I think its not possible put at the beginning again... the question is basically this: something changed in the performance?

my partition now:

Unless your usage patterns cause your system to use the swap file heavily (or you have a system with a low amount of RAM and a large amount of virtual address space committed), there really isn't a noticeable performance hit on faster (7200 RPM desktop or 5400RPM notebook) drives anymore regardless of the file's position. It matters more that it is contiguous, and moving it to a dedicated disk (not partition, disk) can help some, but with a decent amount of RAM your machine shouldn't be using the swap file for much more than file backing and moving idle pages in and out of RAM.

Thank you
