Looking for critiques on my long running webmap project

I'm a ham radio operator and use what's called packet radio frequently. This is a mode that is essentially a computer network over radio. It's useful to know the location of other packet stations so you know where you can "hop" to, by making multiple connections.

So I wrote some Python that automatically connects to different nodes and scrapes the stations they hear. I use an API to get the station locations based on callsign, and these locations are saved in a PostGIS database. I use GeoServer to serve up the layers you see in the webmap.

I'm wondering how I can improve this? Maybe someone has some ideas I can implement? I've tried adding a line layer to show a spiderweb of who can hear who, but it becomes a huge mess and causes the map to lag quite a bit.

This has been my first webmap so I'm sure there's a lot to improve. Please critique away!
