+# 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](https://github.com/wg/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)
