SSL handshake takes over 500 seconds


From Cloudflare documentation: “TCP handshake takes about 50ms”

However it takes around 750ms just for the SSL handshake on our website using Cloudflare

What are we doing wrong?

That article says initial TLS takes 110ms, though I’m seeing around 160ms for mine. Return visits are much faster, though.

In your SSL/TLS settings page, I enabled TLS1.3 with 0-RTT. Firefox, Safari, and Chrome all support TLS 1.3, and the 0-RTT should help on the return visits.
