If your site feels sluggish, run a simple curl -w in your terminal and look at stuff like time_namelookup (DNS), time_connect (TCP handshake), time_appconnect (TLS). A massive JS hydration bundle won't save you if your server is dropping packets or your TLS negotiation takes 400ms.
@pheonix I tried it and it failed though it works without issues in a browser.😩
Turns out my server provided only it's own cert and not the whole chain. 😆
