Benchmarking Nostr event parsing in JavaScript ("leaner" means a very simple and performant binary format):

If these results are right (I'm not sure they are) that means JavaScript is very not-great-at-all dealing with binary things and if Nostr events were designed to be binary from the get go that would entail a massive performance loss for web, react-native and JavaScript clients of all sorts.

I know that benchmarking on the JVM is notoriously hard, because of the JIT compiler and various other non-deterministic factors. So given that most JS engines are also JIT compiled, perhaps the same is true here?

I don't know. My guess would be just that JSON.parse is optimized low-level code while the JavaScript methods for dealing with bytes are super high level abstractions.
