AMD EPYC Performance With FreeBSD 13 Beta

BlogBench, the synthetic benchmark trying to replicate a busy file server, was seeing some significant speed-ups with FreeBSD 13 BETA1. Among other kernel improvements, FreeBSD 13.0 has the latest OpenZFS 2.0 support.

OSBench for looking at the performance of various operating system primitives was showing generally better performance too with FreeBSD 13.

But while the Intel Core/Xeon hardware was showing broad performance improvements with FreeBSD 13 BETA1, that wasn't found with the AMD EPYC Zen 2 benchmarking I have conducted thus far. For the most part in the CPU-bound tasks or where primarily impacted by compiler differences, the AMD EPYC 7F52 server was performing largely the same as FreeBSD 12.
