  1. 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
