It's difficult to tell about consumed memory in ZFS vs UFS since UFS can be quite agressive at caching as well. -(although this caching is often hidden by system tools and reported as "unused" memory)- > > project anyway.

It's much more then resource control! They're really like independent machines with almost no memory footprint. It's quite common to run different zones for a mailserver, webserver and i.e. users. Sparse zones use little space, because lots of code is shared. It's all very tunable. Running 40 sparse zones is hardly noticable.

Because the ZFS checksumming makes the FS selfhealing. Chance for errors are almost nill. No fsck. Yes, it consumes memory, but memory is cheap, very cheap! CPU load is hardly noticable. -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D ++ http://nagual.nl/ + SunOS sxde 01/08 ++ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
