Avoiding complexity

Everyone talks about performance and dreams of short response times for their web application. But the full-stack framework with its powerful ORM and complex code infrastructure, various external libraries and the chronically overloaded database make the goal of a high-performance website a distant prospect. The connection of various, of course, also slow APIs from third parties does the rest. Oh, and e-mails have to be sent as well...

If you follow the "best practices" of many frameworks, all this work is of course done at request time. But the Unix world has shown for decades that the secret of success lies in the interaction of highly specialized and, above all, small applications.

Time to apply this insight to your own code: In this extended session, we will therefore refactor a classically built web application - and simply get rid of everything slowing us down.
