How to delete a directory in Linux? :)?

Question

linux

There are a lot of files in a directory (on ext3).
1. rm -rf damn_dir (thinks for an hour, thinks for two, thinks for a day and won't be born)
2. ls damn_dir | wc -l (see point 1)
3. find damn_dir | xargs rm -f (thinks for an hour and, having filled in 16Gb of RAM, goes into swap and falls into the bark)
4. find damn_dir -type f | while read -r; do rm "$REPLY"; done (see point 3)
Any other options?

Answer 1

find . -delete
Finds and immediately deletes files.
As far as I remember, the other options first prepare the listing, and only then delete it.

Answer 2

find damn_dir -name '*' -exec rm {} \;
