measure (and maybe show) speed of sabctools? #167
Description
Hi @Safihre and @mnightingale
Is this useful, or just nerdy: the speed of sabctools yenc (for reference: versus plain python).
Background: I did this because I'm experimenting with compiler and compiler options on RISC-V
CC=clang CXX=clang++ CXXFLAGS="-march=rva23u64_zbc" python3 setup.py build
and I wanted to know if (or: was hoping that) those options had impact on the resulting sactools speed.
On my x86_64 laptop:
