Possibly this will make the view too slow.

Imagine a slow web service that you consume (ie. a weather service that is used by so many people). Now when your user downloads the page that displays the service's data, they have to wait, because it takes a long time for your app to get the result from the service. With the suggested solution, there is a background task that runs on your server every 15 minutes or so. It fetches the data from the service and stores it in your database. Now when a user wants to see your page, Django gets the values from its own database, so the user doesn't have to wait for your app to get it from the server. As you can see, the tradeoff here is disk usage: you have to store the service's data on your machine. Also, if the data you fetch changes quickly (like in the stock market) this solution is not so good. In this case you may want to fetch the service's data from the generated page, e.g. with AJAX calls.
