Just for some more real-world in-the-field comparisons:
Command line Ant driven xcode 2.2 build of a multi-project medium-
sized code base (for commercially shipping application) building x86
& ppc versions of all the code and creating universal binaries. Code
is mostly C++, Objective C, and some C & ObjC++. gcc 4.0 in all
cases. Full clean and rebuild. Does do a check for new source via
perforce, but full sync was done first so no actual source had to be
acquired (adds a fixed few of second overhead - more for the quad
since it's at home and doing sync over the vpn, but still, just a few
seconds). So, accuracy is not high here but general order of
magnitudes are probably valid with the quad at the biggest
disadvantage due to VPN:
- G5 (early dual 2GHz G5, 1.5G RAM) (not dist build) - 22 minutes 11
seconds
(this machine has seemed slow the last few months and probably has a
hard drive that is overly full or fragmented)
- xserve (dual 2GHz G5, 2G RAM) (not dist build) - 18 min 20 seconds
- iMac dual-core Intel based (512Meg RAM) (not dist build) - 18
minutes 14 seconds
- G5 (early dual 2GHz G5, 1.5G RAM) (With distributed builds to 7
dual 2GHz G5s via switched 100baseT) - 11 min 41 sec
(this machine has seemed slow the last few months and probably has a
hard drive that is overly full or fragmented)
- Quad G5 (2.5GHz, 2G RAM) (not dist build) - 9 min 56 sec
Numbers validate my general feeling - I LOVE MY QUAD G5 ! ! ! :-)

P.S. Clearly the imac needs more ram, but looking at the paging in/
out counts there are very few page outs so it doesn't really seem RAM
bound to me in this case.

The test I did was 18 minutes with an Intel iMac, and 23 minutes
building on a dual 2.3GHz G5 distributing to dual 2GHz G5 and dual
800M G4 (file distribution was over AirPort Extreme, so it was
probably a bit slower than if I were using Ethernet). I haven't
timed a CW 9.6 build in a while, but I think it's right between
those 2 times, probably closer to 18.
