meteor load testing tool complete

[Adrian Lanning]

Initial work on a load testing tool for Meteor applications is complete:

https://github.com/alanning/meteor-load-test

It does a fair job of efficiently simulating clients without requiring changes to the target application.  It utilizes the Grinder to manage agents which execute a customized test script capable of speaking DDP with the target Meteor server. Each agent simulates 1 or more client connections and records performance metrics.  

Users can configure options such as:
 * Meteor methods to call
 * Meteor subscriptions to initiate
 * Number of clients to simulate
 * Wait time between thread start
 * Client ramp-up (process increment)

This tool evolved from discussion on the meteor-talk list: Load Testing Meteor. In particular, I'd like to thank Andrew Wilcox, Sam Hatoum, Matt DeBergalis, and Tom Coleman for their guidance and suggestions.

Wow. This is amazing. I need to give this a try. Looking for something like this so badly.

Fantastic! This is going to come in very VERY handy for our next phase. Also can't wait to get involved

I gave it a try on the included example. It seems HTTP tests are working but tests specific to Meteor (collections and methods) are not recorded.

After some debugging I noticed that the DDP connection is not established.

Can someone confirm or have a fix?

I found a workaround: I removed changes introduced by the pull request https://github.com/alanning/meteor-load-test/pull/4 and it is working.

Thank you, Alexandre. This helped us too.
