D and C# are other C-family languages with similar. LLVM, which allows JIT compilation to multiple architectures, including GPUs; Grand Central Dispatch, which provides very light-weight concurrency; and CLANG, a new compiler which is said to be quite an improvement over GCC. Łukasz reported a 15% performance drop for libego when moving from gcc to llvm. llvm is under heavy development; it has probably improved since. Also, any new technology has both strong and weak points; it takes time to learn how to optimally fit an algorithm to a compiler. Apple reports that recent versions of llvm outperform gcc.
