What is the current behavior?
There is a performance hit when using popups and modals
What are the steps to reproduce?

What is the use-case or motivation for changing an existing behavior?
Angular Material has several performance issues which I think should be addressed.
The web is already slow, no need to make it any slower.
Which versions of Angular, Material, OS, TypeScript, browsers are affected?
@angular/material: ^2.0.0-beta.10
Chrome 61
Is there anything else we should know?
There is a big performance problem related to the modals & popups, I can't figure out what it is. You can often see that animations are slightly stuttering on any device & chrome version after you open a modal/popup. The performance often goes back to it's normal state after a while and sometimes don't which is a real problem, on lower-end device this performance hit is NOT negligible at all.
This bug was probably introduced when the popup/modal system was added which is quite old.
