rushit

rushit is a network micro-benchmark tool that is scriptable with Lua. It resembles well-known tools like iperf or netperf. It originates from the neper project.

The project aims for the sweet spot between a small C program that simulates a network client/server and a fully featured network micro-benchmark. It provides you with a basic multi-threaded epoll-based client/server program that is intended to be extended, as needed, with Lua scripts.

rushit can simulate the following network workloads:

• tcp_rr, a request/response over TCP workload; simulates HTTP or RPC,
• tcp_stream, a uni-/bi-directional bulk data transfer over TCP workload; simulates FTP or scp,
• udp_stream, a uni-directional bulk data transfer over UDP workload; simulates audio or video streaming.

How do I get started?

Best place to start is the project documentation at Read the Docs.

:ref:`introduction` goes over basic usage and available command line options.

:ref:`script-examples` demonstrate what Lua scripting can be used for. Be sure to check out the accompanying :ref:`script-api` documentation.

Don't know Lua?

Don't worry. See Learn Lua in Y minutes for a quick introduction.

Once you are hooked on Lua, take a look at these resources:

• Lua for Programmers blog series
• Programming in Lua book
• Lua 5.1 Reference Manual
• The Lua language (v5.1) cheat sheet

Packages

Fedora, CentOS: In pabeni's copr repository (thanks Paolo!)
