This is the original source of the document: https://gist.github.com/axic/5bf506728005864461454dd4d37a7f37
And it refers to “Appendix C” of https://software.intel.com/sites/default/files/managed/9e/bc/64-ia-32-architectures-optimization-manual.pdf of which @cetrio copy pasted.
Anyway, I wrote it over 3 years so don’t remember where the 80 came from.
@ajoydas Hera wraps 3 different wasm engines. These engines and others were benchmarked by @cdetrio and others. I would need to dig up some slides presenting results. But running evmone benchmark suite in Hera is not directly possible, because these are EVM bytecodes, not wasm.
For EVM benchmarking results see https://github.com/ewasm/benchmarking/.
