Sorry I'm not following. Isn't this a good thing?

Yes, it is a good thing. If you want to contribute code to speed up lemmy_server performance, now the template for caching has been made.

I'm a measly sysadmin. Programming is something I think highly, but posses very little, of, unfortunately. I will probably be among the first to deploy any improvements, though!
