Ah well, if you will use unstable OS releases :-)

The echo has shag all to do with it - it's only echoing once per directory.
No, it's bash all right, or rather the fact that it is a shell, and hence
there's a fork and exec for every directory created and file touched. No
matter how efficient fork and exec are, they're still an overhead. The perl
program, on the other hand, doesn't fork => it's considerably faster.

As Reiser is for me.

Which they would you mean ? There are patches to make Reiser work with NFS -
they're standard with SuSE and I've used them with medium size filesystems
(40-80 GB) with no ill effects.

Haven't used it, but John Allen is running my Perl script as I write with
exactly that version and it's ticking along nicely.

Buggered if I know - check the web site. I know that they plan to start on
version 4 on June 1, FWIW.
