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