Benchmarks Of Ubuntu 17.04 Beta vs. Antergos, Clear Linux, openSUSE Tumbleweed
With all of the tested distributions finally on GCC 6, the performance isn't different for some computational workloads. Then again, GCC 7 will be out shortly and thus the rolling-release distributions may soon be able to benefit from that. GCC 7 will not be found in Ubuntu 17.04.
Clear Linux pulls ahead in the heavy computational tests where its aggressive compiler optimizations and other performance tweaks mean a difference.
