Lon server crashes on startup – what to do?

Is Lon compatible with fabric and neoforge?
Lon officially supports fabric, neoforge for Minecraft 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Lon – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Lon 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.
