I've got a thumper with a pool that has over a hundred million files. I think the most in a single filesystem is currently just under 30 million (we've got plenty of those). It just works, although it's going to get a lot bigger before we're done. > What were the performance characteristics? Not brilliant... Although I suspect raid-z isn't exactly the ideal choice. Still, performance generally is adequate for our needs, although backup performance isn't. (The backup problem is the real stumbling block. And backup is an area ripe for disruptive innovation.) -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
