Introduction
A section for optimising Minecraft servers. Optimising your server means to improve the performance of the server by implementing tweaks without heavily modifying desired mechanics. Advanced optimisation is only recommended for large servers suffering from poor performance.
Spark Profiler
Section titled “Spark Profiler”Use the Spark Profiler for monitoring server performance e.g. vanilla mechanics, plugins, GC pauses and cycles, memory usage etc.
Spark is also able to profile all threads generated by your server using the --thread * flag. You may use this to diagnose high CPU usage, for example.
Server JAR
Section titled “Server JAR”| JAR | Summary |
|---|---|
| Pufferfish | Free and completely stable Paper fork primarily focusing on entity optimizations. Recommended for most smaller networks. |
| UniverseSpigot | Extremely powerful paid fork. Best for the largest networks, being able to hold more than 600 players with ease. |
| Leaf | Free Pufferfish fork. Contains patches similar to UniverseSpigot, though it is not as performant. It’s stability has been called into question, but has worked fine in our testing. |
| Purpur | Paper fork which contains lots of Quality of Life options. |
| Topic | Summary |
|---|---|
| Basic Optimisation | Tweaks that will likely suffice for small to medium-sized servers (< 100 Players) assuming that they have sufficient CPU & memory resources. |
| Advanced Optimisation | Tweaks made for servers that need every drop of performance they can get. |
