Actually I was curious if it would make any difference at all.
The only two "benchmarks" (really they are not) that I have are two different attempts:
find /path/to/temp -type f -exec rm {} \;
This in about 18.39 seconds.
rm -rf /path/to/temp
That finished in 16.43 seconds so you're assumption that the find didn't actually help anything is true.
What I don't have handy is how big those temp directories were or how many files were included (and what size those files were).
Now probably wondering why I can't wait 18-20 seconds but this was just a small test case. The data set will be much larger in normal cases.
Cheers,
Ryan

Do you mean that:-
find /path/to/temp -type f -print >/dev/null
rm -rf /path/to/temp
is faster than just
rm -rf /path/to/temp
or do you mean that you have arranged to do the find before the point
where you want to delete? If the former, that surprises me somewhat.
