LuhnAlgorithmBenchmarking

Comparing Luhn algorithm implementation of popular C# libraries and own methods (includes naive approach, platform-specific and platform-agnostic vectorization approaches).

Disassembly for naive and vectorized approaches is available in the disassembly directory. Currently Windows x86_64 and Linux ARM64 disassembly listings are provided.
