page weight

you enabled load async css , this will add critical CSS inline to the page , so increases the size

I’ve disabled option now, repaired database and optimized. It’s as before. 44kb. Before it was about 25kb.

I see your current homepage is about 34 KB , and with LSCWP bypassed , it gives me 40 KB

What should I do?

I see , that was guest mode page, you can try General -> Guest Mode , disable it and purge all.
