GCC 12 Compiler Optimization Tuning With The AMD Ryzen Threadripper 3990X
The simdjson high speed JSON parsing library did benefit from "-march=native" tuning.
There wasn't too much of a difference with the Zstd performance besides the -O0 run that is without any compiler optimizations. Zstd failed to build with the -Og run.
The SciMark2 benchmarks tend to be very sensitive to compiler changes and tend to greatly benefit from increased optimizations as well as LTO.
