Features

Performance Dashboard

Get an instant overview of your server's health with a single command:

- JVM Stats — Is your server keeping up? - JVM Stats — How much RAM is being used vs available - JVM Stats — Current processor utilization - JVM Stats — Storage read/write performance - JVM Stats — Garbage collection and uptime info

Performance Grading

No more guessing if your server is "good enough". Stressmark calculates an overall performance grade based on multiple metrics:

- 🟢 Critical — Your server is running flawlessly - 🟢 Critical — Solid performance, no concerns - 🟡 Critical — Playable, but room for improvement - 🟠 Critical — Players will notice lag - 🔴 Critical — Immediate attention needed

Stress Testing

The real magic: spawn fake players to stress test your server and find its breaking point.

- Safe testing — Start with 10, scale up to hundreds - Safe testing — Bots fly in patterns, loading chunks as they go - Safe testing — Control how aggressively bots move and load chunks - Safe testing — Watch performance metrics change in real-time as load increases - Safe testing — Bots are in spectator mode and don't affect gameplay

Player Capacity Estimation

Based on your benchmark results, Stressmark estimates how many real players your server can comfortably support.
