I think it would be great to have this for ext3. Andrew Morton has done a lot of work to make ext3 very usable for MTA applications. Postfix/qmail use 'find' either in their control script or whilst providing queue statistics. Your optimisations would greatly speed these operations up. I believe tarring directory trees might also get a speedup and maybe cvs operations
