My understanding is that it's much more than "just" the memory addressing. ZFS is thoroughly 64-bit and uses 64-bit math pervasively. That means you have to emulate all those operations with 2 32-bit values, and on the register-starved x86 platform you end up with absolutely horrible performance. Furthermore, it's just not that well tested. Sun designed ZFS for 64-bit systems and I think 32-bit support was pretty much an afterthought. -- Kirk Strauser _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
