Performance for Angular2+ apps?

The performance measurement is clear in these cases in the video. But when i tested my angular 2 app, looks things different. Like what would be a good performance budget for an angular 2 app? My app is pretty simple, and have: HTML 2.7 kB Images 73.7 kB CSS 282.6 kB JavaScript 1.9 MB

That's looks like too much at start and i don't really see where could i cut the weight.

Then i tested my site on the recommended sites and on them looks like they can't really test it, they stuck on the initial index.html without the real content. The Lighthouse says: First meaningful paint: 9543.6ms (target: 1,600ms) The pagespeed gives me 40/100 and 46/100, says 7 passed and 2 should fix: Enable compression Eliminate render-blocking JavaScript and CSS in above-the-fold content

Although in reality my sites have 1.8 s load time. So it's looks like the Angular 2+ apps performance can't really measured.
