HTTP load tester

Overload

Overview

Overload is a very simple tool for load testing and benchmarking HTTP servers and applications.

Usage

overload [options] URL

Application Options:

-r, --num-requests= Number of requests to make (1)
-c, --concurrent=   Number of concurrent connections to make (1)
-k, --keep-alive    Use keep alive connection

Sample:

jack@hk-47~$ overload -r 500 -c 4 http://localhost:8080/
# Requests: 500
# Successes: 500
# Failures: 0
# Unavailable: 0
Duration: 1.719238256s
Average Request Duration: 13.575435ms

Why another HTTP load tester / benchmark?

ab is broken on the Mac and siege does not support keep alive. Plus, it was fun.

Dependency Management

overload uses godep to lock dependencies.
