HTTP Performance Optimization Techniques

HTTP perfomance

The performance of HTTP is only about the protocol itself.

Why?

Optimization?

The 2 fundament optimization are

• 1. Eliminate and reduce unnecessaty network latency. -a. Reduce DNS lookups -b. Use CDN -c. Keepalive connection -d. Pipelining -e. Using multiple TCP connections -f. Domain Sharding
• 2. Minimize the amount of bytes that need transferrd -a. Make fewer HTTP requests -b. Add cache header(expires, ETags) -c. Gzip assets -d. Concatenation and Spriting -e. Calculating image memory requirements -f. Resource Inlining

HTTP/2

The primary goals of HTTP/2 are reduce the latency by enabling full request and response multiplexing, minimize protocl overhead via effecient compression of HTTP header fields, and support for request priorotizaion and sever push.
