A Linux Compiler Deathmatch: GCC, LLVM, DragonEgg, Open64, Etc...

Open64 had an incredibly strong finish when looking at the performance of its resulting C-Ray binary. Open64's C-Ray binary was over 40% faster than the GCC and LLVM-GCC / DragonEgg releases tested.

Open64 was also produced a blazing fast binary for Himeno that was 93% faster than the second fastest compiler, LLVM-GCC 4.2.1, and 2.6 times faster than GCC 4.5.1.

With MAFFT, Open64 had a smaller but still measurable lead over GCC 4.4.5/4.5.1 while the LLVM-optimized GCC versions were slower than the rest.
