Are these independent benchmarks, or the benchmarketing at namesys.com?
Note that the APPEND, MODIFY, and OVERWRITE phases have been turned off
on the mongo tests and the other tests have been set to a lexical (non
default for mongo) mode. I've done some mongo benchmarking myself and
reiser4 loses to ext3 (data=ordered) in the excluded tests. APPEND
phase performance is absolutely *horrible*. So they just turned off the
phases in which reiser4 lost and published the remaining results as
proof that "resier4 is the fastest filesystem".
