The next step: ETags and network level caching If performance is a serious concern for your API eventually you'll want to stop focusing on optimizing the Web server and instead focus on getting your HTTP caching right. I want to learn more about app users via web analytics. Optimize your processes and get the most from your development. Caches such as Varnish can happily deal with tens or hundreds of thousands of requests per second. Avoiding the premature evaluation of a QuerySet can save making an expensive and unnecessary trip to the database. This hides sensitive data, like instance IDs, by substituting them with a hash. When you reach this level of optimization, you need a formal benchmarking solution. Let's simplify things slightly. Installation Run pip install django-speedinfo. There are a default set of generic views that you can easily use with Django models, and default serializer subclasses that work nicely with Django models, but those pieces of REST framework are entirely optional, and there's absolutely no tight coupling to Django's ORM.

    For the cached case you might be looking at closer to a few thousand requests per second.

    To get results you should run two commands only. Meanwhile, a monitoring agent instruments the code and gathers data not only about the logged exception but also the performance of the functions.

    Note that for our small project, hashing is not really needed, as we can deal without it, but it will help demonstrate some optimization techniques, so I will keep it there.

    The standard JSON renderer also uses a custom encoder that properly handles various cases such as datetime formatting, which in this case we don't need. In this script, I use WSGI application to call view and it gives the possibility to evaluate all the Django flow with middlewares and template rendering.

    this libary relies on indirect (proxy) indicators to performance - e.g.: the number of queries.
    In particular it can show you all the SQL queries your page is generating, and how long each one has taken. Web Development 5. Serializers are really great for providing a standard interface for your output representations, dealing nicely with input validation, and easily handling cases such as hyperlinked representations for you, but in simple cases like this they're not always necessary.

    You can do the profiling yourself, using the built-in Python profiler, or you can use some third party packages for it that are using the built-in Python profiler.

    Dec 6, Application level monitoring encompasses several aspects.

    Line graphs are often not the best solution and they are overused. If it's acceptable for the user list to exhibit a few seconds lag, then we could set appropriate cache headers to that the cache would only re-validate responses from the server after a small time of expiry.

    Sometimes, third-party packages come with a lot of overhead for simple tasks. The overall time also slightly dropped, but there is more space to cut it.

      Tags django, profiler, views, performance. The example code is adapted from a real project that I have worked with and is demonstrative of performance optimization techniques.
