**PulseTest** is a lightweight Minecraft Paper plugin that lets server operators generate controlled CPU and RAM load to test performance and stability. Run `\/stress start CPU ` or `\/stress start RAM ` to simulate load and observe TPS, MSPT and memory behavior.<\/p>\n

## Key Features<\/p>\n

– Start CPU stress by percentage (1%\u2013400%) to simulate main-thread load (intensity is percent of a 75ms baseline per tick).
\n– Start RAM stress by percentage of JVM max heap (1%\u2013100%) with retained allocations to pressure the GC.
\n– Simple commands: `\/stress start CPU|RAM `, `\/stress stop` (stops all), `\/stress status` (shows current status), `\/stress reload` (reloads config).
\n– Safety: configurable max OOM events (default `3`) \u2014 test auto-stops after repeated OOMs.
\n– Fully server-side, no client mods required.
\n– Lightweight, focused, and configurable via `config.yml`.<\/p>\n

## Functionality<\/p>\n

PulseTest provides two compact stressors:<\/p>\n

– **CPU** \u2014 busy-waits on the main thread for a configurable fraction of tick time (uses a 75ms baseline). This lets you simulate varying CPU pressure and observe MSPT\/TPS effects.
\n– **RAM** \u2014 allocates and retains memory in small chunks until a target percent of the JVM heap is reached, holding that memory to pressure the garbage collector. The RAM test will auto-stop after repeated OOMs if configured.<\/p>\n

Use `\/stress status` to see current allocated MB, targets, and OOM counts.<\/p>\n

## Installation<\/p>\n

PulseTest is a server-side plugin. Drop the built JAR into your `plugins` folder and restart or reload your server. Edit `plugins\/PulseTest\/config.yml` to adjust `memory.maxOOMs` (default `3`) and run `\/stress reload` to apply changes at runtime.<\/p>\n

## Disclaimer<\/p>\n

PulseTest intentionally stresses your server \u2014 running high CPU percentages (especially >100% or up to 400%) or targeting near-100% heap can cause large MSPT spikes, OOMs, or crashes. Use with caution on production servers and leave headroom when testing.<\/p>\n
