Server lagging with debug_renderer – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if debug_renderer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
