Map performance is slow due to the used (cluster) algorithm I guess. Since I am not that much interested in the thousands of indoor gateways, let alone single channel packet forwarders, could we split those eg by initially filtering, and/or coloring those?
I really like to have the 1mb json gateway data available at https://www.thethingsnetwork.org/gateway-data/ but maybe we dont really need the global db in one dump for displaying purposes.
Just try to load the map with 3 times that number, and your browser will grind to a halt.
Some lazy loading / pre-select might speed things up.
Thank you,
