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
