If you are using a CDN then it’s easy, just turn it on.
QUIC 3
Over the past 2-3 years we've seen many sites move from 1.1 to 2, a behind-the-scenes upgrade that really improves speed see my link above if you want to read more.
Soon after, a pair of standards known as QUIC + 3 emerged, further portugal mobile database optimizing the connection between browsers and servers, further reducing the number of round trips required.
Super Router
When a user connects to your website, they have to open a network connection to your server or your CDN from wherever they are. If you imagine the Internet as a highway, then you can imagine that they need to "drive" across those roads to get to your server. However, this means traffic jams.
It turns out that some of the big cloud companies have their own private roads that are smoother, have less traffic, and have increased speed limits. If your website visitors have access to these roads, they can "drive" to your servers much faster!
If you use AWS, you can use their Global Accelerator . This allows your site requests to use their private network and get a potential speed boost.
Summary of key points
Key Point: Many of these benefits are easier to obtain if you use a CDN. If you aren’t already using a CDN, you probably should be.
Key Points: TLS 1.3 is now very widely supported and provides significant speed improvements for new connections.
Key Points: QUIC3 is only beginning to gain support, but will become more widely available in the coming months. QUIC includes the benefits of TLS 1.3 and more. Today a typical 2 connection requires 3 round trips to open; QUIC only requires one!
