I don't have the two on comparable machines :-( Do you have a standard benchmark for comparing the relative performance FileStorage/DirectoryStorage on reiser fs?

...

Mmmmm. I suspect NTs heavier file security checks will prove to be a significant disadvantage - benchmarks to follow.

If you do benchmarks, you should do them comparing DirectoryStorage/NTFS to DirectoryStorage/reiserfs, because (at least at mass object creation) DirectoryStorage is slower than FileStorage (because of the open() overhead). I plan on optimizing the random access on huge number of objects case.
