Indeed,
+% mkdir test
+% time perl -e 'foreach $a (1..10000) { open FOO, ">test/$a" }'
1.490u 72.550s 1:31.65 80.7% 0+0k 0+0io 287pf+0w
+% time sync

+% time rm -rf test

But that's a p133 running linux, run of the mill 2G SCSI disks.

Heh -- my mail.misc has 16000 files, mail.personal has 6500... and I
usually enter them with 33 or 99 (whatever is easiest to type) to read
new stuff, or maybe 300 or so if I want to search back a bit. *That*
isn't slow... but when I hit $ to refile some spam, from mail.misc to
mail.spam (which only has 600 messages at the moment) it takes as long
as 5 to 10 seconds to recover. I'd guess most of that has to do with
rewriting the 3.5M .overview file in mail.misc -- having 64M of RAM
does help, especially with linux aggressive caching...
Needless to say I'm pushing gnus quite a bit here. All I really need
to do is write some scripts to refile all of mail.misc during 1996
into archive.1996.mail.misc, or something like that...
