Tornado Benchmarks

This is a simple app, like a blog, displays blog post retrieving from database. I used MongoDB as data store and Tornado for routing and templating. Tornado is running behind an nginx proxy.

This is how it looks once loaded:

There are 3 apps (or Tornado servers). They are:

1. Uses pymongo and fetches data synchronously
2. Uses motor and fetches data asynchronously
3. Combination of tornado-redis + motor

Then I used siege tool to benchmark:

siege http://app.iavin.com/5427f88aa76036081aa5edbe -c10 -t10s

Here are the results of each:
