Chat Calculator server crashes on startup – what to do?

Server lagging with Chat Calculator – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Chat Calculator consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
