GCC 6.2 vs. Clang 3.9 Compiler Performance On Clear Linux With Intel Kaby Lake

GCC 6.2.0 was also much faster with the C-Ray multi-threaded ray-tracer.

While Clang was faster with Crafty.

The LAME MP3 performance was close to the same.

The tests ended out with Clang outperforming GCC with the OpenSSL benchmark.

Clang 3.9 on Clear Linux did win in a number of tests while GCC still also dominates in a number of benchmarks too. Perhaps most surprising from these benchmark results today were the compilation times with GCC 6.2 compiling code significantly quicker than Clang 3.9.
