That is an incorrect statement. Reiserfs is KNOWN to be heavier on CPU
than other filesystems, it's benefit is not there, it's benefit is in
speed of operation, and efficiency of disk accesses. It would be near
impossible for a filesystem with 4x (unsure of this figure) the code of
ext3 to execute in the same CPU time, but the fact that it is
consistently a LOT faster on the total run time is very impressive.
