With the ray-tests in Bullet, LLVM Clang-produced binaries took a strong first place finish.

With using the FLAC binaries produced by LLVM and Clang, the WAV to FLAC audio encoding performance was not as optimal as the GCC binaries.

With the HWB Color Space conversion test in the Open MP-based GraphicsMagick, the LLVM Clang 2.9 SVN performance on the Core i7 2820 QM notebook was faster than GCC 4.6 with the corei7-avx optimizations, but both were much slower than the AVX-lacking GCC 4.5.2/4.6.0 builds.
