Server lagging with Structure Restrictions – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Structure Restrictions consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
