MogileFS does a number of verifications per file store. So the write 
performance isn't very optimised right now.

You can get significant overall write performance by doing writes more 
in parallel. Have you tried firing up multiple processes writing 10k 
files each? They _should_ finish all about the same time, and without 
taking much longer than a single process would otherwise.
