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
