Starting from today, all CloudFlare websites are loading almost twice faster than before. Cloudflare enabled HTTP/2 for all accounts that enabled the SSL/TLS connections, even for the free customers.

According to a CloudFlare blog post, “If you are a customer on the Free or Pro plan, there is no need to do anything at all. Both SPDY and HTTP/2 are already enabled for you”.

One large benefit of HTTP/2 is the ability to use a single TCP connection from a browser to a website. In this way, all CloudFlare users can see the benefits of HTTP/2, which is to accelerate the web surfing experience between browsers and CloudFlare, without the need for the customers to change anything on the origin server.

As you can see in the above image, there will be only one connection instead of using a separate connection for each file. Thus, the website will load much faster. This image is probably the best comparison example between HTTP/1 and HTTP/2.

Cloudflare also provided the page load improvements:

Access via HTTP Protocol Version Average Page Load time
HTTP 1.x 9.07 sec.
SPDY/3.1 7.06 sec.
HTTP/2 4.27 sec.

Cloudflare remember us how much browsers offer support for SPDY over HTTP/2. If Cloudflare won’t offer anymore support for SPDY, more than 50% of it’s users will see lower page load time. That’s the reason why Cloudflare will continue to support both SPDY and HTTP/2.
