Running BSDs On The AMD Ryzen 5000 Series - FreeBSD vs. Linux Benchmarks
For some workloads, compiling with Clang can still offer measurable build time improvements compared to GCC but that is becoming less common these days.
Some of the wins, of course, are due to Ubuntu 20.10 making use of GCC over Clang by default.
It was an interesting round of benchmarking overall and FreeBSD 12.2 generally was coming up close to Ubuntu Linux to provide for healthy competition.
