>From what we've read on the mailing list, the 1.6 compiler performance improvement is about forking parallel threads to compile the different permutations in parallel. But each permutation is still compiled from scratch on every pass, due to the large number of global optimizations being applied, and the unique symbol generation being applied at the very end.
So no, I don't think 1.6 will bring a way to pre-compile code and reuse the pre-compiled library during subsequent application builds. But if you have 1 CPU per permutation, you may be able to see the compile time drop down to 1/NCPU of what it is now.
