README

This is in reference to https://plus.google.com/105596541985629444566/posts/27y819XoT2V
to show simple steps I took to try and reproduce the described issue based upon the
information available. This is very simple benchmarking with an almost vanilla Rails 4
application using sqlite as the database so is not useful other than to demonstrate the
out of the box performance with TorqueBox and Trinidad under these situations is very
close.
