(4xMPI) DONE Raw: 34034 c/s real, 34034 c/s virtual Benchmarking: dynamic_27: FreeBSD MD5 [SSE2i 4x3]... (4xMPI) DONE Raw: 67824 c/s real, 67152 c/s virtual Benchmarking: dynamic_28: Apache MD5 [SSE2i 4x3]... (4xMPI) DONE Raw: 68388 c/s real, 68388 c/s virtual Apparently, the condition that enables the use of intrinsics is not the same for md5 vs. dynamic_27 and 28, and apparently it is non-optimal for md5 for certain gcc version(s) (I guess Apple's gcc 4.2). Would you look into this, please? Thanks, Alexander
