Fedora, Ubuntu, CentOS, openSUSE, Debian, Clear & Antergos Linux Benchmarks On AMD EPYC
First up are some of the I/O tests with SQLite being the first at bat. With the small variation in results, Antergos / openSUSE Tumbleweed / Clear Linux were lining up as the fastest while noticeably slower than the rest were Fedora Server, CentOS 7, and Ubuntu 16.04.3 LTS. Common to Fedora Server and CentOS 7 are the use of XFS by default: openSUSE also has XFS but with its newer kernel appeared to offer better performance. Clear Linux, openSUSE Tumbleweed, and Antergos are all making use of the current stable Linux 4.13 kernel.
Ubuntu 17.10, Fedora Server 26, and CentOS 7 were all delivering the best random read performance with FIO.
While on the random write front, there isn't as much difference in the performance across the nine tested Linux distributions.
As a good sign for next year's Ubuntu 18.04 LTS, Ubuntu 17.10 was delivering the fastest sequential read performance.
With using NVMe storage where no Linux I/O scheduler is being used, the results don't tend to be too different between Linux distributions compared to using a SATA/SAS SSD or rotational media.
With DBench, the XFS-using Linux distributions were the fastest in this multi-threaded disk benchmark.
