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.
As Django has matured it's being used for bigger and bigger projects. Lets talk about ways we can measure performance so we can see if the.

It's important to have a clear idea what you mean by 'performance'. Python provides a number of tools for lazy evaluation, particularly through the generator.
A Guide to Performance Testing and Optimization With Python and Django. Iulian Gulea. There are several things we can measure in a project: Execution time.
For the cached case you might be looking at closer to a few thousand requests per second.

Not all performance improvements are worth the effort. Let's take the extreme approad and drop all middleware from the settings and see how the view performs.

7 Python and Django Performance Optimization Tips Actually, lazy evaluation tools can help you achieve significant performance gains. Performance testing for Django through your automated tests!
Django Performance Optimization Tips
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.
