How unfortunate we missed your precious stance on that matter. Everybody
knows that benchmarks are mostly useless /per se/, however it often
occurs that comparative benchmarks may easily reveal some interesting
differences.
As for the interest of an experiment of pushing something to the limit
for the sake of it, it may equally reveal interesting bugs. The fact
that all filesystems in this tests didn't simply *fail* under the load
is by itself revealing of the overall robustness and stability of
these, the VFS and Linux kernel.
As a side note, were you using a slightly less harsh tone, you'd
probably be help people being less reluctant to discuss those points
more deeply.
