Performance Issue: Potentially making the theme useless in a production setting

[tomthor]

Recently I've been trying to optimise the starter theme as it has a rather high TBT score:

I haven't been able to reduce it by a significant amount. Could this be because of the way the starter theme has been coded? Is this fixable using optimisation or is it an unfortunate reality of this starter theme?

From my experience, having a next app, will always have a low score due to loading tons of js. Usually a next js app scores around 60%, but don't make this a priority, next is fast even on first load, the metrics doesn't know how to calculate the complexity of the app.
