Server tuning

Some tuning lives in the server’s own config files, not xLimbo’s. For a fallback server that a whole network may land on at once:

server.properties

view-distance=4
simulation-distance=4
spawn-protection=0
allow-nether=false

xLimbo sets view and simulation distance on its own world, but the server-wide values still apply to any other world. Set online-mode=false only behind a proxy with secure forwarding.

spigot.yml

Lower the entity-tracking-range values and merge-radius, and keep view-distance in step with server.properties.

Paper and Pufferfish

In config/paper-world-defaults.yml (and pufferfish.yml on Pufferfish), tighten entity activation ranges, stop ticking entities far from players, and keep max-auto-save-chunks-per-tick low. xLimbo runs with autosave off anyway.
