Debugging Luanti Server Performance Issues
Watch as we troubleshoot and fix massive performance bottlenecks in our Luanti (Minetest) game server proxy in real-time! CPU usage spiked from 70% to 400%, and we discovered the root cause and solution live on stream.
Our proxy server running in Docker started experiencing severe lag with 200MB memory usage and 120-400% CPU spikes. Players were getting massive packet loss and the server was essentially DDOSing itself.
Example of live debugging, performance optimization, and why understanding protocol differences (TCP vs UDP) matters for game servers!
