Ubuntu 21.04 Server Performance Offering Nice Gains For AMD EPYC 7003 Series
Python 3.9 is in use for Ubuntu 21.04. The Python benchmark results were mixed relative to Ubuntu 20.10 but at least generally ahead of where it was at a year ago with Ubuntu 20.04 LTS.
When looking at 94 different test cases run across the three Ubuntu Linux releases benchmarked on this AMD EPYC 7763 server, Ubuntu 21.04 was in front more than half the time and taking the geometric mean of all 94 benchmarks shows Ubuntu 21.04 about 6% faster than Ubuntu 20.10.
So while Ubuntu 21.04 is not a Long Term Support release, if you are not in need of LTS requirements this may be a release worth considering for having a nice performance bump in many workloads at least on newer hardware platforms. Ubuntu 21.04 benchmarks on more systems will be coming soon now that the Ubuntu 21.04 "Hirsute Hippo" official release is set for Thursday. Overall on the various systems I've been testing Ubuntu 21.04 I have been very happy with the performance and overall experience.
Aside from any performance gains of relevance to you, Ubuntu 21.04 is also important for AMD EPYC 7003 "Milan" users if running the default kernel. The newer Linux 5.11 kernel on Ubuntu 21.04 means working temperature and energy sensor support for Zen 3 server processors among other additions and new kernel features in general.
