What Unix would that be?
% mkdir test
% perl -e 'foreach $a (1..10000) { open FOO, ">test/$a" }'
% time rm -rf test
0.60u 11.18s 1:55.40 10.2%
% uname -a
SunOS heimdal 5.5.1 Generic_103640-08 sun4u sparc

ls is primarily slow because it has to sort the files.
But of course, the Unix filesystem gets slower as more files are in a
directory, but it's not _that_ bad.
