32 active Beacons (full base) in a relative small area cause the fps to drop drastically

I know the setup is overkill, but I wanted to try this for some asthetic effects. When the beacons aren't powered on I get unlimited frames per second. When I start to activate them one by one, the fps starts to drop rapidly. Once all 32 beacons are activate, I hardly get 5-6 fps

The dips in the red of the alt-f3 screen are when I look away from the beacons. No beacons have any status effect set.

The beacons are placed at the bottom of the world (Bedrock removed to go as low as possible)
