[LRUG] API automation / load testing

[Ed James (Alt)]

Thanks Alex. I've been using jMeter for a while now and for the most part it's fine. I was wondering if there were any more Ruby/Rails oriented tools that could be incorporated into our project, but it looks like for now I'll be sticking with jMeter for development and probably blitz.io for production. 

Tourbus looks very cool though, so I'll take a closer look at that too.

Thanks.
