I'm now prepearing to either create a swap file or a swap partition. I am interested in knowing if there is any difference in performance. Anyone have any experience with this? Thanks.
A swap partition would be faster (think about it -- no filesystem overhead). The only reason for a swap file is if you didn't plan your partitioning scheme properly, and _need_ to add swap at a later date.
Sorry, I don't have specific benchmark numbers for you. I'm not sure how one would even go about benchmarking such a thing.
Oh, you can also have multiple swap partitions, on different drives. If you set them to the same priority, it will use all at the same time. Kinda like a raid0 stripe, but without creating the software raid. If you're concerned about stability, I think you can software raid the drives first, and then create a swap partition on them (haven't actually done this myself, since raid would damage performance).
