Google's own lighthouse suite runs everything through network/cpu throttling for scoring so to download a bundle that started at 2mb and parse it really penalizes you compared to a 1mb bundle (even after gzip and you're getting screwed on parse performance of lower devices). Then you have the way universal replaces all content when it bootstraps and you get penalised for that. We're also seeing issues where the site isn't ready yet and clicking a link just opens a new tab cause the JS wasn't downloaded/parsed yet. You can use the preload library but guess what: doesn't work. As usual it was always: this'll get fixed with ivy and it wasn't. It seems all libraries we depend on were initially made by staff who were driven out of the team. - universal - animations - forms Our clients use the Google performance scores and ask why none of the performance improvements we're doing has had any effect and then point to a React competitor's lighthouse score
