I think you missed the discussion of TMPFS vs UFS performance. Creates in
TMPFS are going to be orders of magnitude faster than in UFS. The same is
not true for EXT2FS. All the benchmarks show that there is little or no
difference; in fact, at this point, on similar hardware, I would guess that
EXT2FS is actually faster than TMPFS - Sun's code is a bit heavyweight.
