Phoronix: GCC 4.9 vs. GCC 5.3 vs. GCC 6.1 On A Debian Xeon E5 Linux System

Given the recent stable release of GCC 6 (GCC v6.1.0), here are some fresh compiler benchmarks on an Intel Debian x86_64 system when comparing the GCC 4.9.3, GCC 5.3.0, and GCC 6.1.0 compiler releases.

Same question. Are there some performance tests showing if the compiler produces faster code at all? Might also be interesting to see how the code compares against LLVM/Clang.

LLVM Clang results coming in a day or two.

It seems rather pointless to test on a Xeon as it doesn't reflect the overwhelming majority of users or developers configuration.

What do you think of build servers?

IMHO the compilation time is the least important figure when comparing compilers. The following should matter a whole lot more: code quality, standards compliance and code size.
