Very Many Players
A Fabric mod designed to improve server performance at high playercounts.
VMP is still in early development and things are expected to break. Please report any issues to our issue tracker.
So what is VMP?
Very Many Players, or VMP for short, is a Fabric mod designed to improve general server performance at high playercount
without sacrificing vanilla functionality or behavior.
For the best performance it is recommended to use VMP with Lithium.
How VMP achieves its performance improvements?
Server-side game logic performance improvements:
- Uses area maps to optimize nearby packet sending and player lookups
- Uses cache to optimize entity trackers, fluid state lookups and ingredient matching
- Optimizes entity iteration for collisions
- Optimizes ticket propagator using MCUtil from the Paper project (patch licensed under MIT)
Client-side game logic performance improvements:
- Makes time source to use built-in Java time source instead of GLFW via JNI calls
Networking performance & responsiveness improvements:
- Uses our own chunk sending mechanism (optionally with packet-level rate-limiting)
- Adds packet-level per-player render distance
- Makes vanilla tcp connections more responsive using packet priority from raknetify
(works best when the server is connected without reverse proxies such as velocity and ssh port forwarding)

What counts as many players? 10? 20?
pls make a forge version
What does this actually do tho
What does this actually do to increase performance ?
Would be nice if the description gave a lil run down of how the mod actually improves server performance
Honestly, this is really impressive of what you guys have been able to do, well done!
