When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:

| kCenters[1, ] <- df[whichPoints[1], ] # Initial center |
| # this feels weird, but there's some magic here. Ruby knows where 'rubygems' is without you having to explain it with an exact path. | |
| require 'rubygems' | |
| # now you can you just flat-out require ANY gem you have installed! like | |
| require 'pony' | |
| # all of the sudden you have this really cool ruby library called 'pony' in your application's object space! And you can do shit like this: | |
