Not useful at all! These tips are mostly not useful except Production Webpack Mode. Please don't share wrong information. Increasing Chunks and using CDN makes your app perform very low.
Increasing Chunk's lets browser which bundle to cache and which to load first in order to reduce first content paint full.
Also, please learn more about CDN's. Don't act foolish CDN's are used by almost every website in order to cache static content and rapidly transfer the data to users' browsers.
Any ways thanks for the awesome tip's next time I request you to learn about a stuff before negative rating stuff.
Also, a quick answer to use web.dev and not use CDN
