< p > When your application runs slow, throw some caches in. Well, at least
it’
have a function that takes some time to complete but the results would
still be good enough if they were 5 minutes old. So then the idea is that
you actually put the result of that calculation into a cache for some
time.< / p >
< p > Flask itself does not provide caching for you, but < a class = "reference external" href = "https://flask-caching.readthedocs.io/en/latest/" > Flask-Caching< / a > , an
extension for Flask does. Flask-Caching supports various backends, and it is
even possible to develop your own caching backend.< / p >
