It has already been six months since AMD introduced the EPYC 7003 “Milan” processors which continue to perform well and gain market share. While the recently released version of Ubuntu 21.10 is not a Long Term Support (LTS) version, for those wondering what this latest Linux distribution means for the performance of the EPYC 7003 series, here is a look at its performance across many benchmarks compared to that of Ubuntu 21.04 which was released just after the Milan launch, then Ubuntu 20.04 as the current LTS stable series.
Basically what is looked at today is the performance of the same AMD EPYC 74F3 ASRockRack server in testing:
– Ubuntu 20.04 LTS server as the current long-term stable version used in the company. Ubuntu Server 20.04.3 LTS defaults to the original Linux 5.4 kernel and other non-HWE packages.
– Ubuntu 21.04 as a non-LTS version which debuted shortly after the launch of EPYC Milan.
– Ubuntu 21.10 as a recently released non-LTS Linux distro for those wondering about the current out-of-the-box performance of AMD EPYC servers on this release, which is also now six months ahead of Ubuntu 22.04 LTS.
– Ubuntu 21.10 with upgrade to Linux 5.15 Git for the very latest kernel version close to its official release in the coming weeks.
So here is how Linux performance has evolved since the launch of the AMD EPYC 7003 series from Ubuntu 21.04 to 21.10 and more broadly how the latest performance is compared to Ubuntu 20.04 LTS, if the LTS designation is not important to you or just curious about the gains on the table by getting closer to Ubuntu 22.04 LTS.
This series of Ubuntu Linux benchmarks was performed on an ASRockRack ROME2D16-2T currently under review at Phoronix with a frequency-optimized 24-core AMD EPYC 74F3 Zen 3 server processor with 8 x 8 GB of DDR4 memory -3200. The only changes made between runs was a clean install of Ubuntu Linux each time, then with the final run also an upgrade to Linux 5.15 Git with the operating system each time, otherwise left to its values by fault.
