http://code.google.com/p/unladen-swallow/source/detail?r=1015 has significantly improved this situation. The new table of incremental build times: +-------------+---------------+---------------+-----------------------+ | Incr make | CPython 2.6.4 | CPython 3.1.1 | Unladen Swallow r1024 | +=============+===============+===============+=======================+ | Run 1 | 0m1.854s | 0m1.456s | 0m6.680s | +-------------+---------------+---------------+-----------------------+ | Run 2 | 0m1.437s | 0m1.442s | 0m5.310s | +-------------+---------------+---------------+-----------------------+ | Run 3 | 0m1.440s | 0m1.425s | 0m7.639s | +-------------+---------------+---------------+-----------------------+ The remaining increase is from statically linking LLVM into libpython.
