About this Mod

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).
