Realtime Benchmarks

Does some benchmarking of popular Realtime Hosted Services. You can see the current stats on the Realtime Hosted Service Latency Stats page.

The services that are currently benchmarked are:


The client directory contains the benchmarking code and some stuff required to build it (concat the files).

Within src/public/js you'll find BenchmarkRunner.js. This class runs the tests.

The src/public/js/BenchmarkService.js class is an abstract class that defines how each of the services should be benchmarked.

  • Each of the classes that inherits from this must override the send and disconnect functions and act appropriately when they are called i.e. when send is called it should send the provided message.
  • When the implementation is ready to be benchmarked it should call onReady on the provided listener.
  • When the implementation receives a message back it is expected to call onMessage on a listener object that is provided to the constructor.
  • If the implementation wants to log anything it can call onLog on the provided listener.
  • Each implementation is given a channel name that it can send message on, if required.

Testing and Developing New Benchmarks

A development server can be run using foreman.

› cd client
› foreman start

Basic code required to provide some historical and realtime latency on the Realtime Hosted Service Latency Stats page.

This includes and endpoint for consuming new results and uses Faye to deliver realtime updates to the latency stats page.

It's a bit of a mess right now and needs some refactoring


Some code for fetching and analysing the results that have been captured since Sun Oct 28 2012 12:52:01 GMT+0000 (GMT).

Note: Calling the results endpoint will only return the last 10 results. If you'd like a copy of the raw data then please get in touch.


Code that is used to faciliate the benchmark tests and store the results.
