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.
