Removing huge amount of files and directories is a long operation, no matter what file system you have in use. Depending on your I/O subsystem and file system it might help performing the removal in parallel; just put one rm process removing directories starting with a-f, another one with g-n, and third one with o-z. Or something like that.

Or if it's OK for you to just have file removal going on background, you can always

mv data data_to_be_removed
mkdir data
rm -rf data_to_be_removed

    Just what I was in the process of suggesting, Janne - I completely agree with you. Computers are there to do hard work that takes time, so we don't have to. mv the file system to one side, then rm -rf can be happily chewing through it freeing up disc while you get on with putting your new content in place. – MadHatter Oct 28 '11 at 8:39
