Ubuntu 21.04 Server Performance Offering Nice Gains For AMD EPYC 7003 Series

For those relying upon the WireGuard open-source secure VPN tunnel, WireGuard on this AMD EPYC server was running faster with the new Linux 5.11 kernel.

For various HPC workloads when sticking to the same GCC compiler throughout, there isn't much of a difference.

The LuaRadio software-defined radio framework using the distribution's default Lua packages were showing performance regressions in some cases using Ubuntu 21.04.

At least with the GNU Radio SDR package, it's seeing better performance on Ubuntu 21.04 with this AMD EPYC server as found out-of-the-box on each release.
