Http bENCHmarking tool

hench

The Http bENCHmark tool.

Installing (requires go 1.2 or newer):

$ GOPATH=`pwd` go get github.com/spotmx/hench
$ sudo cp bin/hench /usr/local/bin/

Running:

$ ./hench -rps=1 -script=simple.lua

Usage:

$ ./hench -h
Usage of ./hench:
  -keepalive=true: Use keepalive connections.
  -rps=10: Maximum number of requests per second.
  -script="simple.lua": The lua script to run.
  -workers=100: Number of workers to use (number of concurrent requests).

Pushing it to the max

$ ulimit -n 100000
$ GOMAXPROCS=`cat /proc/cpuinfo | grep processor | wc -l` ./hench -rps=10000 -workers=200 -script=simple.lua

You might need to run this as root because of the ulimit.

You might also need to increase -rps if it's already reaching the 10000.

Now increase -workers until the number of requests per second doesn't go any higher.
