Yes, but at least for my development style, I end up compiling every
file many times. Xcode could keep track of how fast it was to compile
each file on each computer available and then use that information to
decide how to distribute the files to build. It wouldn't likely change
too much between edits. It also could likely make a decision based on
how many lines the files were, how many files were to be compiled, etc,
and do better than it does now.

The problem is that finding out how long a file is going to take to
compile is just as hard as compiling said file - so there's no way for
XCode to tell if it will be faster to ship the file out or keep it
in-house. The only thing that it might be able to do is go "oh...
I've finished building all my stuff and I'm waiting on my partners, I
might as well see if I can beat them to the punch" and start compiling
something another box had been told to build.

Hi Dix,
I've noticed the same thing you are. If I'm compiling a lot of
files, the distributed build wins hands down, but if it is only one
or two files it is actually slower than not using the distributed
build. I'm using a powerbook G4 1.25 GHz and my distributed
partners vary from dual G5s to a 450 MHz Cube. Perhaps we should
file a "bug report" on this.

Hi,
is there any way I can tell XCode to prefer the local machine for
building? Or just set the order of preference which machine gets to
work? It doesn't matter if I am doing a complete build but when I
need to compile only 1 or 2 files I think it would be faster to use
the local machine than to push all the stuff around the network. In
my case it would be a lot faster since my local machine is a G5
while the remote machine is a lowly G4...
Thanks,
Dix
