There were some changes in R-devel that can make it slower, but not noticeably I suppose. Can you test the CRAN binary of R-devel (from http:// r.research.att.com) to see if it exhibits the same slow-down? FWIW the full flags used for the CRAN i386 build are the following: CC="gcc-4.0 -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk" CXX="g++-4.0 -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk" F77="gfortran-4.0 -arch i386 -isysroot /Developer/SDKs/ MacOSX10.4u.sdk" FC="gfortran-4.0 -arch i386 -isysroot /Developer/ SDKs/MacOSX10.4u.sdk" CPPFLAGS=-msse3 CFLAGS="-g -O2 -std=gnu99 - march=nocona" CXXFLAGS="-g -O2 -march=nocona" FFLAGS="-g -O2 - march=nocona" FCFLAGS="-g -O2 -march=nocona" --enable-BLAS-shlib -- with-system-zlib --enable-memory-profiling Using the universal SDK supposedly results in faster executables, but I didn't test it ...
