Description (last modified by Natalia Bidart)

urlize will check every word for whether it is a url (and then updates the url to be a html link).
We can add some form of caching so that it doesn't repeat the checks on the same "word"

PR: ​https://github.com/django/django/pull/18665

Benchmarks:

Before:

>>> import cProfile
>>> from django.template.defaultfilters import urlize
>>> cProfile.run("urlize('Django. ' * 1_000)")
         61048 function calls (59047 primitive calls) in 0.030 seconds

After:

>>> import cProfile
>>> from django.template.defaultfilters import urlize
>>> cProfile.run("urlize('Django. ' * 1_000)")
         3783 function calls (3702 primitive calls) in 0.005 seconds
