Real fun this moment. It took appoximately 13 hours on a two socket, 8
core Dell PowerEdge 1950 III at 2,5 GHz with 16 GB RAM for 453 ports to
be recompiled.

I have another box (of many) running FreeBSD 8.0-BETA2/amd64 with 2 GB
RAM and a Athlon64 2,2GHz CPU having 800(!) ports installed. Can you
imagine how long this box will be occupied by 'portupgrade -af'? I guess
'cherry-picking' is the only solution.

FreeBSD 8.0 on AMD64 does have serious performance issues these days,
try to compile a compiler (gcc44, for instance) and watch how bumpy your
X11 or how network traffic on a 'headless' server becomes. Kernel
compilation time has been increased by approx 10 minutes on the 8 core
box with 16 GB RAM since ~ 4 months now. I know, this is a kind of off
topic for the questiojns discussed at the moment, but I guess those
problems and fun are guaranteed for those having lots of ports, FreeBSD
8 running on AMD64 ;-))

Oliver
