Can I reduce load with randomTickSpeed / gamerules?

Gamerules and a few config tweaks can shave a little load off your server. They won't transform a struggling server on their own, but combined with the bigger optimizations they help at the margins.

What gamerules can do

• Lowering randomTickSpeed (for example, /gamerule randomTickSpeed 2) reduces how much crop growth, leaf decay, and fire spread the server processes each tick.
• Disabling gamerules you don't need — such as mob griefing or patrols — trims unnecessary work.
• Capping mob spawns in spigot.yml limits how many entities the server has to track.

How to apply them

1. In the Console, set a gamerule directly, e.g. /gamerule randomTickSpeed 2.
2. Disable rules you don't need the same way, e.g. /gamerule mobGriefing false.
3. For mob-spawn caps, edit spigot.yml via the Files tab and restart.

Tip: These are marginal gains. The big wins come from switching to Paper, pre-generating your world, tuning view-distance, and having enough CPU/RAM — do those first, then use gamerules to squeeze out a bit more.

Frequently asked questions

Will lowering randomTickSpeed break farms? It slows crop growth and similar processes, so automatic farms produce more slowly. Choose a value that balances performance against how your farms behave.

Are gamerules enough to fix serious lag? No — they help at the edges. Pair them with Paper, pre-generation, and appropriate resources for real improvement.
