  So, I've narrowed down the slowest part of the request to the generation of email temlates. I'm not sure exactly what makes it slow, but I don't think it's related ot queries. I can reduce the time the view for saving high fives takes by 10 seconds if I just don't render the template.

- The first part of this ticket moved all the user mention and notification processing into a celery task. That task, however, is still very slow. It takes over 8000k and around 60 seconds to complete on a local server. Some ideas were already initiated and they can be found in a draft branch – https://github.com/15five/fifteen5/compare/dev...ENG-12288-optimize-high-five-save-view--test
