Perhaps, but the current command looks at every file at every depth. I
had a build of seamonkey on my /tmp directory and just did:
cd /tmp/seamonkey
time find . -xdev -mindepth 1 -delete -print
and got every file printed and
real 0m20.987s
user 0m0.457s
sys 0m2.833s
Perhaps
find . -xdev -mindepth 1 -maxdepth 1 ! -name lost+found -exec rm -rf {} \;
would work better.
