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.
