Day 32 -cache, cache, cache

I really wish we had server logs out of the big sites, especially Lemmy.ml, and statistics on API calls.

I really feel like a crash course of adding a cache layer to reading comments and posts is what the project needs more than anything.

Somebody is probably going to do it, I expected with all the attention on the project, but I could probably knock it out in 40 hours for comments and posts and keep it smart and still only use a modest amount of RAM (512MB, 1GB, or 2GB) for what Lemmy.ml level has now.

We are talking massive improvement under busy load, even if you re-read from SQL every 60 seconds.
