in reply to BerkeleyDB vs. Linux file system

ext3 have not any advantage over ext2 in respect of efficiency, it might be even a bit slower due to keeping the journal.

    ext3 is slower, for the reasons you describe--it has to do everything ext2 does, plus a journal. Since it uses ext2 as a base (not just the fs itself, but the code implementation), it is impossible for it to be faster than ext2.

    ReiserFS is totally different. From the benchmarks I've seen, it's generally slower than ext2, but faster than ext3. YMMV.

    Update: Minor grammer mistake fixed.

    This is a good point. I think that what has improved in this case is really the kernel and the VM system, not the file system itself.
