Oh ok, yeah, if you preload the binary, it's a good measurement (of parsing + optimization). And yeah, it's common that most code is not used early. Browsers are implementing baseline JITs to help there, so they only fully optimize necessary code. I don't think any browser landed that yet though. Another option here is dynamic code loading, if you know some code is only needed later, you can load it yourself (dlopen, etc., which is supported already).
