A few weeks ago I posted some results for the evaluation speed
calibration (Analyse|Evaluation speed). For compiler options see

A few speed measures (values in static ev./s):

AMD Athlon XP 1600+, Win2k, gcc 3.2

CFLAGS  = -O -mms-bitfields
14200 - 14300

CFLAGS  = -O -mms-bitfields -march=pentium-mmx -mcpu=pentium-mmx -mmmx
14300 - 14400

CFLAGS  = -O -mms-bitfields -march=athlon-xp -mcpu=athlon-xp -msse
14700 - 14800

CFLAGS  = -O3 -mms-bitfields
15750 - 15820

CFLAGS  = -O3 -mms-bitfields -march=pentium-mmx -mcpu=pentium-mmx
-mmmx
16400 - 16500

CFLAGS  = -O2 -mms-bitfields -march=athlon-xp -mcpu=athlon-xp -msse
16700 - 16850

CFLAGS  = -O3 -mms-bitfields -march=athlon-xp -mcpu=athlon-xp -mmmx
-m3dnow -msse
16980 - 17030

CFLAGS  = -O3 -mms-bitfields -march=athlon-xp -mcpu=athlon-xp -mmmx
-m3dnow -msse -mfpmath=sse
17100 - 17150

CFLAGS  = -O3 -mms-bitfields -march=athlon-xp -mcpu=athlon-xp -msse
17100 - 17170
