My computer is in a weird state at the moment with other projects, so I wouldn't trust my numbers anyway.

The build loads all of your VIs and the libraries into a build context. If the VIs are in memory, it transfers those from the intel context to the PPC context, compiling and loading alternate libraries as needed from disk.

If the VIs are kicked out of memory, the VIs will all be loaded from disk into the new context. From what I saw last year, both routes performed compiles they didn't need to, but the bugs were reported and some of the biggest ones were fixed. My suspicion is that the disk route will be faster, but it would be helpful to do both and please post your results.

I ran a few tests on my Xeon machine, it averaged about 58 seconds with the VIs open and 59 with them closed.
That machine is probably more disk limited then it is memory which could explain the results. I will test some more latter tonight/tomorrow on a slower machine and see if the difference between them increases.
