Ubuntu 20.04.2 LTS / 20.10 / 21.04 Performance On Intel Xeon Scalable Ice Lake
In some cases Ubuntu 20.04.2 LTS still delivered the best results as we have seen from compiler regressions, kernel changes, and other factors.
Rust compilation such as for building Wasmer we have found to improve very nicely with Ubuntu 21.04 compared to 20.04/20.10 across a wide range of platforms.
Granted, it shouldn't be too surprising that the latest Ubuntu release tends to perform the best with the latest hardware.
PostgreSQL in some scenarios saw the database server running much faster with Ubuntu 21.04.
