LLVM 2.9 Clang Performance On Intel's Sandy Bridge

The John The Ripper DES performance was similar across all four tested compilers.

While John The Ripper's DES test had performed the same regardless of whether GCC or LLVM was used, with the MD5 performance the LLVM + Clang compiler had fallen behind to almost half the speed as the GNU Compiler Collection.

The Blowfish performance was also in bad shape for LLVM Clang at being just over half the speed of the GCC 4.5/4.6 performance.
