I've spent my career ping ponging between writing fast low level code for games, and online systems. If you want to talk about high performance code, benchmarks are a requirement. There's no numbers here. It only talks about "Robust", which OP defines as: > By robust I mean no undefined behavior for any input, valid or invalid; no out of bounds accesses, no signed overflows. Input is otherwise not validated. Invalid input may load as valid by chance, which will render as either garbage or nothing. Robust is a baseline for high performance programming.
