My stats for what they are worth:
Compiling a large project with > 1000 C++ source files takes over 30
minutes to build on my Dual 1 GHz MDD machine. Due to the specifics of
the source code, we are unable to use a pre-compiled header. :-(
Distributed to a total of 10 CPU's (random machines in the office: 1
dual 1 GHz, 2 dual 450s, 2 PB G4 500s, 1 733 and a 1 GHz PB) build time
is down to about 10 minutes. That's a 66% improvement in build time and
a lot of gained productivity.
Obviously the faster the machines you can throw at the build, faster it
will go. Our initial distributed build on just the dual 1 GHZ and 2
dual 450s improved things a bit but not much. We had to get the other 4
CPU's in to really make a difference.
Also, getting G5's can make a huge difference. Our client can build the
same code base on a single 1.8 GHz G5 in 15 minutes (half the time of
my dual 1 GHz machine). I'm theorizing that given those stats, a dual 2
GHz machine will build the code in 7-8 minutes. I'd actually test that
but my G5 has not left the factory yet... :-(

Does anyone know if there's a test project available that I can derive
some metrics relating to time spent compiling for 1, 2, 4, etc
systems? Our project isn't converted yet and has lots of issues that
need to be changed before we can move to gcc3.3. So what I want to do
is show management that converting to gcc3.3 along with getting
additional distributed Xcode processors is worth it. Currently we
suffer extremely long compile times, but numbers speaks the truth so I
need something to develop real world metrics from.
