Change server version
If you are using a version above 1.12.2, it will make a LOT of difference if you change the version to a stable version. (Everything under 1.12.2)
Resolving / Avoiding Errors
Some plugins give errors and can cause lagg problems on the server. For this reason, we always recommend to resolve all errors.
Remove unnecessary plugins & worlds
By removing unnecessary plugins and worlds, the server will have to use less resources, which can prevent lagg.
Due to the excessive use of resources, the server sometimes says that it can no longer handle it, causing the server to crash & lag.
This can be solved very easily by upgrading the server.
Lower the view distance
This can be prevented by reducing the view distance in a server. View distance determines the number of blocks a player can view in the server. This can be set lower in server.properties, ArmyHost itself recommends setting it to 5 lower is of course always better.
By using a worldborder, players cannot load an infinite amount, which means that the server will also be less lagging.
The worldborder plugin can be downloaded by (clicking here).
It is always good to restart the server every 12 hours, for example.
This ensures that all the loaded terrain on the server is deleted.
By using anti-lag plugins, the server needs to use much less performance, so that lagg can be prevented.
Here are a few plugins that can help with that.
It may help by optimizing Spigot.yml/Bukkit.yml/paper.yml, do this by following the following article https://www.spigotmc.org/threads/guide-optimizing-spigot-remove-lag-fix- tps-improve-performance.217260/ or https://www.spigotmc.org/threads/guide-server-optimization%E2%9A%A1.283181/?__cf_chl_jschl_tk__=pmd_3c65683b1c9181f6a9bec5118332b53157785a19-1626812823-0-gqNtZGzNAg2jcnBszQi6.
