    There is a guy doing fragmentation testing for reiserfs. It turns
    out that (in his tests) reiserfs can get 10x slower as the filesystem
    fills up because of intra-file fragmentation. I don't know enough
    about reiserfs block/file allocation policy to know how this compares
    to ext2 at all.

    See http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/agetest.html

    Cheers, Andreas
