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.
