PERFORMANCE
The numbers that describe server health, and the settings that move them.
- 7 entries
- Concept reference
Server performance is measurable, which is unusually good news: rather than guessing, you can watch ticks, memory, and chunk activity and see exactly where the time goes. The vocabulary is small — TPS, MSPT, heap, chunk, entity — but the numbers behind it decide whether a survival world feels smooth.
These entries define the metrics, explain what each resource actually does for the server, and point at the settings that reliably change them.
Minecraft Server RAM: How Much You Need and Why
How RAM works on a Minecraft server: heap versus system memory, how much to allocate, why claiming more than the machine has causes crashes, and how to size it.

Minecraft is mostly single-threaded, so per-core speed matters more than core count. Learn what the main server thread does and how to spot a CPU bottleneck.

Minecraft TPS explained: what ticks per second measure, why 20 is the target, how TPS differs from MSPT, and what each TPS range actually feels like to players.

MSPT explained: milliseconds per tick is the honest measure of server health. Learn healthy values, how to read spikes versus steady load, and where to find it.

How Minecraft loads and generates chunks, why generation causes lag spikes, what pre-generating a world achieves, and how view and simulation distance differ.

How Minecraft limits entities: mob caps, cramming, and collision behaviour, why piled-up mobs cost ticks, and the settings that reduce entity load safely.

View distance versus simulation distance: what each controls, how they multiply server load, sensible values for small servers, and how to change them safely.
