For a very small instance with only a couple of concurrent users a CDN might not make much difference. But if you take a look at your web server logs you’ll quickly notice that every post / like / vote triggers a storm of requests from other instances to yours, looking up lots of different things. It’s easy to imagine how quickly this would overwhelm an instance once it gets even a little busy.

One of the first web performance tools people reach for is to use a CDN, like Cloudflare. But how much difference will it make? In this video I show you my web server logs before and after and compare them.

    Yeah, my response was a bit tongue-in-cheek because one of the things that I don’t like about Lemmy is this coupling to a specific storage backend. Maybe it was just immaturity of actix that led the devs to take this approach, but most mature web frameworks already allow pluggable storage backends, so in the end it seems that Lemmy will reinvent a bunch of wheels.
