Testing on old hardware is flawed

Please don't test filesystems on old hardware. Current hardware has totally different cpu-speed/disk-speed ratios, while both the speed of the cpu and disk have risen tremendiously.
Reiserfs 4 has been written for modern hardware. It has no place on old hardware. And since there are no conversion tools available, there is no viable upgrade path anyway.
It would be really interesting to benchmark again on a > 2 Ghz machine with a disk which does > 40 MB/sec, in at least 512 MB of ram. Such a machine would be at the low end where reiser4 installations will occur (not because reiser4 won't work on older hardware, but just because most installations will occur on new hardware).
One of reiser4's problems on older machines is the high cpu usage. On modern hardware this problem will be less visible, since cpu power has outgrown disk speed by an order of magnutude.
