CentOS 6 Through CentOS 8 Benchmarks On Intel Xeon Server

The network performance has improved nicely with CentOS 8 but can be much better without mitigations.

Facebook's Hackbench shows the advancements made by the Linux kernel scheduler with time.

Over the span of many workloads (more documented here on OpenBenchmarking.org) shows the gains made from CentOS 6 to 7 and now CentOS 8 on this Xeon Scalable server. Going from CentOS 6 to 7 on this Skylake server meant 17% better performance while from CentOS 7 to 8 yielded 30% uplift. Or in going from CentOS 6 to CentOS 8 is a 53% uplift out-of-the-box. On CentOS 7 with the tests carried out was 11% higher performance when disabling mitigations while on CentOS 8 is 13% higher performance.
