A non-rigorous, C-only, release-checking bootstrap (which showed me that I forgot to change the release-checking TREE_TYPE macro, oops!) make -j4 on a lightly-loaded-ish quad-core machine gave these numbers: without patch real 10m8.397s user 33m18.060s sys 2m43.300s with patch real 9m57.203s user 33m12.660s sys 2m44.090s So noise-ish territory. I suppose a more fair comparison would be just the gcc/ directory, and those non-rigorous numbers, from a 'cd gcc && make && time make -j4' post-bootstrap are: without patch gcc/ real 2m41.307s user 8m0.180s sys 0m30.950s with patch gcc/ real 2m35.716s user 7m55.050s sys 0m30.160s Of course, these numbers were only measured once, so they are non-definitive, etc. etc. -Nathan
