CentOS Stream 9 Improves Performance For Intel Xeon, AMD EPYC

There are some Python performance improvements with CentOS Stream 9, but as shown Intel's Clear Linux continues shipping an aggressively optimized Python package.

Likewise, the default PHP package on CentOS Stream 9 is much faster than CentOS Stream 8 (granted, there are application streams for opting to a non-default newer PHP version and the like on CentOS/RHEL 8).

Those wishing to look more at these results and even more data can see this OpenBenchmarking.org result file for all of the data points in full for this initial CentOS Stream 9 benchmarking. In 2022 will be many more CentOS Stream 9 performance tests to come. Long story short, as expected, CentOS Stream 9 does provide better out-of-the-box performance over CentOS Stream 8 on modern hardware.
