I noticed that speed difference, too. After running ./configure, I
edited the resulting Makefile to pass "-march=athlon-mp" to the C
compiler. ./configure seems to ignore CFLAGS, for example, so I just
edited Makefile to suit my environment. You should set the values
appropriate for you system, of course.

I've also compiled Python using the Sun Studio compiler. Some tests
were faster, some tests were slower.
