Original, unupdated/dead version: ClearLag Datapack

This datapack is advanced as it uses methods from server software like Spigot and Paper to optimize performance!
You can configure many settings and even enable a small anti-crash for your server, which prevents extreme lagging using armor stands.

Click on the message on reload or use the following command to change the settings:
function clearlag:menu

Works on vanilla, bukkit, spigot, paper, all forks of paper and modded servers.

The methods this datapack uses to reduce lag:

• Shorter item/experience orb despawn time (important items and items after dying wont get removed)
• Automatic clears which remove all items in a configurable interval
• Freezes unused entities
• Merges experience orbs
• Removes collision from farm animals

Also, the data pack is really performant so it shouldn't create any lag on its own.

Note: You should always prefer server software such as Paper because it has a lot more customizable options and overall performance that data packs can never reach. You should only use this datapack if you cant use another server software, or you still have a lot performance issues.
