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).

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)

1. Simple HTTP benchmark

This benchmark requires three terminals running:

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