Can you recommend something? I use an ext4 filesystem.
Without actually trying to to see, I suspect that a C program that calls remove() would probably be faster than just about anything else.
I agree with what you are saying, and I think you may even want to use unlink() if they are all files, no dirs. remove() actually will call unlink() so you may be able to save few function calls and logical statements.
I doubt saving functions calls is going to gain you anything in this case as 99.9% of the time the rm takes is on disk I/O. If you want to reduce the rm time you have to find a way to reduce the disk I/O it requires.
