I thought of a better way to phrase it. The website itself is fast, but the process of you observing the website is slow because of limitations of the speed of light (or other interconnects the internet uses to get your traffic to Helsinki).

I think what you’re saying is that if OP were to test your site from Helsinki they would see the server speed you’re talking about. Is that right?

Yeah, unless I can find a CDN to cache my blog (and maybe its static assets) that would be affordable enough for my needs.

I wrote an article about making server-side rendered sites fast around the world without a CDN at https://fly.io/ruby-dispatch/semi-static-websites/

My examples are in Ruby, which is super slow compared to what you’re doing. Now I’m super curious what kind of performance you’d get globally on Fly if you deployed to a bunch of different regions.

If you can help me get a Nix flake running on Fly, I'll try it!

I know next to nothing about Nix at Fly except there's a few folks who are looking at it at Fly. The repo at https://github.com/fly-apps/nix-base shows how its working for a Rails app. Is that enough to get you running with Nix flakes?

Beyond that https://community.fly.io is the best place to get help with Nix on Fly since my abilities are exceeded. There's a Rust thread at https://community.fly.io/t/running-reproducible-rust-a-fly-a... that touches on nix flakes.
