ProjectileSpeedLimiter
ProjectileSpeedLimiter caps how fast entities may travel on a Fabric server, so unusually high speed values cannot destabilize it.
What it does
The mod sets a ceiling on entity speed values and keeps them within reasonable bounds. Its purpose is to prevent server crashes that can occur when experimental features push speed beyond what the game handles. Although the name refers to projectiles, the limit applies to entity speed in general. It is installed on the server only, so players join without any mod.
Key features
Speed value ceiling
Entity speed is capped at a reasonable value, below the 1,000 blocks per tick level that can cause crashes.
Crash prevention
The cap is aimed at server stability when experimental settings allow very fast entities.
Normal travel unaffected
Ordinary movement, including entities moving fast in normal play, continues without interference.

Limits speed values in Minecraft to reasonable values to prevent a server crash whilst using experimental minecarts. Although the mod is called Projectile Speed Limiter, it actually works by preventing the speed of any entity to exceed 1,000 blocks per tick (20,000ms -1 ). This should never impede on normal gameplay…
