Let me give you a small example of what situation we currently have:

For this test i used the core/primitives_test.cpp test and g++ 4.5

Phoenix3 total compile time: 3.421s
Phoenix3 preprocess time: 1.755s
Phoenix3 compile time of preprocessed code: 1.835s

Phoenix2 total compile time: 1.891s
Phoenix2 preprocess time: 0.745s
Phoenix2 compile time of preprocessed code: 1.106s

comparing with clang:

Phoenix3 total compile time: 3.901s
Phoenix3 preprocess time: 2.738s
Phoenix3 compile time of preprocessed code: 1.273s

Phoenix2 total compile time: 2.015s
Phoenix2 preprocess time: 1.320s
Phoenix2 compile time of preprocessed code: 0.788s

These timings may not be very represantative, but show in what state we 
currently are, and that there is a high potential to reach phoenix2 compile 
times.
