Benchmarks The choice of filesystems on Linux is vast, but most people will stick with their respective distributions' default choices, which will most likely be ext3, but you're free to use ReiserFS, XFS, or something else completely if you so desire. Things are about to change though, with btrfs just around the corner. To bridge the gap between now and btfrs, ext3 has been updated to ext4, which adds some interesting features like extents, which are already in use in most other popular file systems. Phoronix decided it was time to do some performance checking on ext4.

linux caches a lot in RAM and in SWAP.

Linux caches a lot in swap?

When you have 4GB of SWAP and 2Gb of RAM, a lot of the changes you made is not commited when the test ends.

With 2GB of ram and only bonnie++ running, I should hope that swap would not be relevant! (Well, as long as the fs in use is not ZFS. ;-) ) At any rate, bonnie++ fsyncs at the appropriate times. I presume that the other disk benchmarks do so, as well. The other tests, like lzma, were not suitable as disk benchmarks to start with.
