[Braindump] Fabianx' Drupal 8 performance master plan

Is this issue still needed?

#2 is definitely still relevant, render context is currently tracked in a static property, although we should open a dedicated issue for it.

Opened 📌 Refactor the render context stack to avoid a static property Active .

I think #4 is very similar to 📌 Entity lazy multiple front loading Active - in purpose if not implementation, and also 📌 Add PHP Fibers support to BigPipe RTBC .

That leaves #5.

So should this be moved back to NW?

Yeah there's still things to extract from this one. Let's make it a plan.
