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).

Comparisons

Check out the Github README for comparison GIFs, or gallery.

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.

Frequently Asked Questions

Does Fast Server Pings need to be installed on the Minecraft server?

No. Modrinth marks Fast Server Pings as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Fast Server Pings require?

Use a file for fabric and your exact Minecraft version. Supported versions include 26.3, 26.3-rc-3, 26.3-rc-2. Files for different loaders are not interchangeable.

Fast Server Pings is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
