Arch Linux CachyOS Benchmarks Of x86-64-v3 & x86-64-v4 Repositories
For workloads being built by the user from source and without any compiler flag changes to those applications under test, the underlying operating system package differences didn't equate to any performance gains in the benchmarks tested.
Code compilation though was consistently faster using the x86-64-v3 or better packages.
Not much of a difference was observed in the system-supplied OpenSSL.
There were a few advantages to the x86-64 feature levels for the OpenSCAD open-source 3D CAD modeller provided by CachyOS.
