Using gcc 4.6 on macosx I am getting good increased performance:

Standard 64-bit build:
./john -test -format:raw-md5
Benchmarking: Raw MD5 [raw-md5 64x1]... DONE
Raw:	4498K c/s real, 4544K c/s virtual

./john -test -format:md5
Benchmarking: FreeBSD MD5 [32/64 X2]... DONE
Raw:	10170 c/s real, 10170 c/s virtual

./john -test -format:raw-sha1
Benchmarking: Raw SHA-1 [raw-sha1]... DONE
Raw:	2882K c/s real, 2911K c/s virtual

32-bit SSE2 build:
./john -test -format:raw-md5
Benchmarking: Raw MD5 SSE2 [raw-md5 SSE2 16x4]... DONE
Raw:	10678K c/s real, 10786K c/s virtual

./john -test -format:md5
Benchmarking: FreeBSD MD5 [32/32]... DONE
Raw:	6581 c/s real, 6581 c/s virtual

./john -test -format:raw-sha1
Benchmarking: Raw SHA-1 SSE2 [raw-sha1 SSE2]... DONE
Raw:	7076K c/s real, 7076K c/s virtual

64-bit build w/ SSE intrinsics code:
./john -test -format:raw-md5
Benchmarking: Raw MD5 [raw-md5 SSE]... DONE
Raw:	13606K c/s real, 13743K c/s virtual

./john -test -format:md5
Benchmarking: FreeBSD MD5 [12x]... DONE
Raw:	25104 c/s real, 25104 c/s virtual

./john -test -format:raw-sha1
Benchmarking: Raw SHA-1(8x) [SHA-1]... DONE
Raw:	7695K c/s real, 7773K c/s virtual

Although, md5a fails the benchmark test,

./john -test -format:md5a
Benchmarking: Apache MD5 [12x]... FAILED (get_hash[0](0))
