Benchmarking `node-http-proxy`

The long-term goal of these scripts and documentation is to provide a consistent and well understood benchmarking process for node-http-proxy so that performance does not degrade over time. They were initially created to compare the performance of v0.10.3 and v1.0.0 (which was a significant rewrite).

Pre-requisites

All benchmarking shall be done with wrk which is the same tool used for performance testing by the node.js core team. Make sure you have wrk installed before continuing.

$ wrk
Usage: wrk <options> <url>                            
  Options:                                            
    -c, --connections <n>  Connections to keep open   
    -r, --requests    <n>  Total requests to make     
    -t, --threads     <n>  Number of threads to use   
                                                      
    -H, --header      <h>  Add header to request      
    -v, --version          Print version details      
                                                      
  Numeric arguments may include a SI unit (2k, 2M, 2G)

Benchmarks

Simple HTTP benchmark

Simple HTTP

This benchmark requires three terminals running:

A proxy server: node benchmark/scripts/proxy.js
A target server: node benchmark/scripts/hello.js
A wrk process: wrk -c 20 -r 10000 -t 2 http://127.0.0.1:8000
