LLVM Clang 3.7 vs. GCC Compiler Benchmarks On Linux
GCC was slightly faster than Clang when it came to audio encoding with the FLAC audio format.
The PostgreSQL server performance was nearly the same between GCC and Clang.
With the Apache web server, the Clang 3.7 performance now matches that of GCC 5.2.
Well, those are the initial benchmarks I've done so far of the near-final Clang 3.7 build compared to the GNU Compiler Collection. Coming up will be the OpenMP benchmarks once I have that working properly. Once again, there's more daily benchmarks of the LLVM/Clang code (already at 3.8 SVN) via LinuxBenchmarking.com. All of these benchmarks are done in a fully-automated and reproducible manner using the open-source Phoronix Test Suite and Phoromatic projects. While the LinuxBenchmarking.com tracker covers both Intel and AMD hardware, for another Phoronix article to complement today's tests I'll also work on some AMD and ARM compiler benchmarks. As always, feedback is welcome and if you appreciate the testing please consider helping out.
