Template rendering performance

I just realised, that if I delete all scribbles from my template, the template rendering times are 100-300 ms shorter (measured by https://pypi.org/project/django-debug-toolbar-template-profiler/ with user logged off).
This is significant performance issue for me, since it can be 1/3 or more of the whole request time.

I will investigate this further.

Start by reproducing the reported 100–300 ms difference with django-debug-toolbar-template-profiler, comparing a template with and without scribbles while logged off. Then trace the rendering path to identify where scribbles add overhead. Done means the cause is isolated and the performance impact is reduced or clearly characterized with a regression measurement.
