This .exe was compiled with ICL 4.5 with the following options in a 3 step process: 1. "nmake -f Makefile.MSVC PROF_OPT=GEN OPT=ULTRA" 2. The created file was then run through some common functions such as encoding and decoding to generate a profile. 3. "nmake -f Makefile.MSVC PROF_OPT=USE OPT=ULTRA" This creates an .exe which uses profile guided optimization, which seems to allow a slight speed increase (2%-5%). This .exe should be as fast or perhaps slightly faster than Mitiok's "fast" compiles.
