My build times have gone from a minute or so to several minutes per. I believe the only thing significant I added were assets. The problem I have now is that build iterations are almost unbearable. I typically play with several things in a different scene before trying them in the full build.
Also, is it possible to do a distributed build? I have other machines I could leverage.
Im using the MacOSX version on an i7 / 4GHz / 16 GB RAM.
