HTTP/1.x and HTTP/2 protocols are compared

In HTTP/1.x, clients must use multiple TCP connections if they want to make multiple parallel requests to improve performance

In HTTP/1.x, clients must use multiple TCP connections if they want to make multiple parallel requests to improve performance (see Using multiple TCP connections). This is a direct result of the HTTP/1.x delivery model, which guarantees that only one response per connection is delivered at a time (response queuing). To make matters worse, this model can also lead to header blocking, resulting in inefficient underlying TCP connections.

The new binary framing layer in HTTP/2 breaks these limitations and enables complete request and response multiplexing: the client and server can break down HTTP messages into frames that do not depend on each other, send them in a staggered manner, and finally reassemble them on the other end.
HTTP 2.0 greatly improves web performance, and further reduces network latency on the basis of full semantic compatibility of HTTP 1.1. Achieve high throughput with low latency. For front-end developers, optimization efforts are reduced.
