How much memory you have? How big is mozilla-1.5a.tar? Did you include 'sync' in the tests? It seems reiser4 numbers are mostly in-memory operations and not all data flushed to disk while this is apparently not true for ext3. BTW, XFS numbers would be also/more interesting, ext[23] is pretty

mozilla-1.5a.tar is mozilla 1.5alpha source tar, uncompressed. Partition mkfs.ext3 or mkfs.reiser4 --keys=SHORT is run before each run. Linux is 2.6.0-test2. untar mozilla-1.5a.tar (file is on a reiser3 partition): ext3: 17.64s 28% cpu reiser4: 10.79s 67% cpu sum: reiser4 0.61x time, 2.39x cpu
