Add a simple benchmark for Navigator.handlePage#926
Merged
Conversation
I'm going to do some hacking around in here and I want to make sure I don't hork performance. Don't have a harness for this or anything yet. Mostly just pushing it up so I don't lose track of it.

This takes some work that used to happen for each request and caches it. This is mostly groundwork for fine-grained instrumentation of page lifecycle methods. It incidentally also slightly reduces the overhead of building up the page chain object during each request. [core/__bench__/handlePage.js](redfin#926) before: ``` 1 0.000481308279135711 10 0.0009405891195623999 100 0.005067864883424908 1000 0.04754033069230767 ``` [core/__bench__/handlePage.js](redfin#926) after: ``` 1 0.0004272630582241284 10 0.0006927164659505115 100 0.0034683026867557273 1000 0.031324801985714294 ``` Basically reduces middleware overhead to from ~50µs to ~30µs. Not a huge deal, but the instrumentation is likely to add a little overhead, so it's nice to pay some of that down ahead of time. 😁
