Improving Performance and Reducing Requests

[nickcharlton]

Now we've got a good chunk of stuff working, I'm trying to plot out what we'll need to get it all working in production. The most common example is the ISS, so I'll use that. So, for example:

import spacebodies

sb = spacebodies.SpaceBodies()
events = sb.next_events("iss", lat=50.7184, lon=-3.5339)

On my system, it takes 22.6 seconds for the next_events call. Considering most of that is network access:

1. How many calls are we making to Forecast.io? It looks like 3.
2. What can we cache locally that'll help?
3. Which bits of data are only updated daily or less?
