Vaadin app performance ....

I have a simple touckit app and when I use Google’s PageSpeed Insights I get a score of
48/100
.

https://developers.google.com/speed/pagespeed/insights/

PageSpeed tells me that the app needs to enable compression to reduce transfer size. How do I enable compression?

It also ask to eliminate render-blocking JavaScript and CSS in above-the-fold content and to Optimize CSS Delivery of the following: How do I perform this?

also how do I set minify=true?
