Binary Data Transfer Benchmark for WebSocket-Node

This benchmark reports client -> server -> client binary data transfer latency on websocket and calculates the throughput (kbit per second). The binary data is randomly generated, and the websocket protocol is version 13.

Dependencies Install

$ npm install

Quick Start on localhost

$ npm install
$ node app.js&
$ node client.js 1048576 5

Arguments

app.js [https=false]

• If the first argument is given, app.js starts listening to https (and wss). If this option is on, app.js requires server.cert and server.key files.

client.js dataSize, numberOfMeasurement, [https=false]

• The first argument is dataSize (Bytes) in decimal to send.
• The second argument decides the number of Measurements for averaging (denominator of average).
• If the third argument is given, client.js uses https (and wss).

Tips

In order to quickly calculate the dataSize, `echo "2^20"|bc` tricks can be useful. For example, benchmarking 1MiB (= 2^20) data transferring performance, use

 $ node client.js `echo "2^20"|bc` 5

In order to run on a remote server, edit client.js and change the serverName.
