RE: sudo find / > /dev/null takes 61 seconds...

Well, find is known for being one of the biggest resource hogs in UNIX - an=
d find / is particularly brutal.  Watch your usage levels with vmstat next =
time you run find / ...

A tip:

Instead of:

find / -name "blah"

Do this ahead of time:

find / | ls -l > /.filemaster

Then your find command gets changed to this:

grep /.filemaster "blah"

=2E..and it goes lightning fast and doesn't hog system resources.
