Benchmarks

Benchmarks log each request/response pair while returning 'hello world', using autocannon with 100 connections and 10 pipelined requests.

• http-ndjson (equivalent info): 7730.73 req/sec
• http-ndjson (standard minimum info): 9522.37 req/sec
• pino-http: 21496 req/sec
• pino-http (extreme): 25770.91 req/sec
• no logger: 46139.64 req/sec

All benchmarks where taken on a Macbook Pro 2013 (2.6GHZ i7, 16GB of RAM).

Install

npm i pino-http --save
