Do you have any benchmarks? I don't, but two years ago I tried swapfiles and the box lagged on high-load/swapping.

You do not mount a swap partition: /dev/swap-device none swap sw 0 0 (Note mount-point is none.) And a swapfile needs: /dev/partition-with-swap-file /mnt/swap ext3 defaults 0 0 and then: swapon /mnt/swap/path-to-swapfile (ext3 as an example only) Regards, Norberto -- [EMAIL PROTECTED] mailing list
