Description
Stressmark
Know your server's true limits.
Stressmark is a server-side mod that helps you understand exactly what your Minecraft server can handle. Whether you're preparing for a big event, choosing hosting specs, or just curious about your hardware's performance, Stressmark gives you the answers.
Features
Performance Dashboard
Get an instant overview of your server's health with a single command:
- TPS (Ticks Per Second) — Is your server keeping up?
- Memory Usage — How much RAM is being used vs available
- CPU Load — Current processor utilization
- Disk I/O — 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:
- 🟢 Exceptional — Your server is running flawlessly
- 🟢 Good — Solid performance, no concerns
- 🟡 Fair — Playable, but room for improvement
- 🟠 Poor — 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.
- Spawn any number of bots — Start with 10, scale up to hundreds
- Realistic movement — Bots fly in patterns, loading chunks as they go
- Adjustable speed — Control how aggressively bots move and load chunks
- Live monitoring — 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.
