This is highly important since Google will reduce the ranking of web sites based on their performance evaluation, starting June 2018!
I had a look at them and to be honest, I'm the opposite of impressed.

There are also style sheets than can be combined and minimized.
This need some rework for a huge perfomance boost when rendering.
