Answer 1

We were facing the same issue. Here are couple of things that I did to improve the performance of Angular App:

1. Improve images loading time images consumes most of the time while page loading so images should be compressed. I developed on the fly image compression system in AWS to handle this. https://docs.aws.amazon.com/solutions/latest/serverless-image-handler/appendix-d.html

2. Use change detection strategy on push in most of your components

3. Unsubscribe your observables

4. Use async tag js script tags in index.html

5. use pagination or infinite scroll loading in application
