Install in the game only; not needed on the server
FastServerPings
A client-side mod that rewrites the Minecraft server ping pipeline, designed to scale properly with large server lists and make refreshes feel smoother.
Server pings are scheduled across the entire list rather than strictly top to bottom, with results handled using SWR (stale-while-revalidate).

Compatibility
FastServerPings intentionally replaces the vanilla Minecraft server ping pipeline. Mods that modify, redirect, or otherwise depend on the vanilla ping server implementation may therefore be incompatible unless explicitly supported.
