Measuring element perf "cost"
There has been much work recently around optimizing paper element elements, from dynamically creating ripple events, to removing styles, and much more.
I would love to come up with a list of measurable metrics that we want benchmark against. I know that using the debugger is super useful to find what is eating up a bunch of time locally, however at a "framework" or component level doing reproducible verifiable perf work is really really really hard.
From this list, I can then do some work around creating a tool that we can run on CI to give us some hard numbers for every single element.
the initial metrics that I am thinking would be....
- GC thrashing
- event listeners
- node count
(your ideas here!) :sparkles:
Thanks :exclamation:

Would it be useful for this work to look at per-element first paint times too?
