Run a Lithium server
The standard server optimization mod — same vanilla behavior, much cheaper ticks.
Installs automatically · Live in under 30 seconds · No port forwarding
Lithium is the rare optimization mod with a hard promise: it does not change game behavior. No disabled mob farms, no altered redstone — the same vanilla logic, executed cheaper. That's why it's the default first install on serious Fabric servers.
It compounds with good hardware rather than replacing it: high-clock cores set your ceiling, Lithium makes sure vanilla's worst tick paths don't waste them.

Questions, answered.
Does Lithium change vanilla mechanics?+
No — that's its design rule. Farms, redstone and mob AI behave exactly like vanilla; the work is done in how the logic executes, not what it does.
Do players need Lithium installed?+
No. It's fully server-side; vanilla clients join normally.
How much difference does it make?+
It depends on the world — the wins come from entity AI, hoppers and chunk logic, which are exactly what loaded farms hammer. Busy survival servers typically see substantially cheaper ticks; your console's TPS readout will show it.
