It may be that there's no way to break that 1-hour barrier.  Maybe I
can convince Colin that, until full cross-compiling is available, we
sparc64 folks would settle for slightly-delayed binary security
updates (instead of never getting them at all).  It's the very fact
that we're running on slower hardware that makes freebsd-update so
attractive.

I'd still like to see what a quad Ultra 80 can do, though. :)  Who has
access to one of these?

Chris, did you do any of the other things that the handbook
'Rebuilding "world"' section suggests -- noatime /usr/src, async
/usr/obj, etc?  Also, are you tracking 6.2-STABLE, -RELEASE, or
something else?  If -STABLE, as of when?  Over time, these data points
may be relevant.

This'll do until we come up with something better:

Thanks!
