HTTP2

The performance benefits of HTTP/2 come from simultaneous/parallel (pipelining) and batch requests. For example based on my tests, HTTP/2 was able to handle 500,000 requests (30sec~) but HTTP/1 barely managed 100 requests with many "broken pipe", "connection reset by peer" errors. The tests issued requests as in goroutines.

cannot read input protocol buffer message, Error: read tcp internalIP:8080->outerIP:17194: read: connection reset by peer, in protocol: HTTP/1.1 from:publicIP host:logging.domain.vn, X-Client: , X-Client-Rip: ripIP

why is golang http server failing with broken pipe when response exceeds 8kb?

HTTP2 là gì?

Tổng quan HTTP2

https://viblo.asia/p/tong-quan-http2-aWj53OEQ56m

Mục tiêu chính của HTTP/2 là reduce latency (giảm độ trễ) bằng cách:

• kích hoạt full request và response đa kênh,
• giảm thiểu gánh nặng cho các giao thức truyền thông bằng cách nén có hiệu quả các HTTP headers.
• Ngoài ra nó còn hỗ trợ việc đánh ưu tiên các request và Server push

HTTP/2 Push là gì, dùng preload hay HTTP/2 Push thì tốt hơn
