How to Install Spark and Run a Spark Profiler on a Minecraft Server

Spark is a lightweight, high-performance profiling plugin for Minecraft servers. It helps identify performance bottlenecks such as TPS drops, heavy plugins, or overloaded threads. With Beacon Hosting, setting it up is quick and easy.

Step 2: Install the Spark Plugin

You can install Spark in two ways:

• Automatic installation (via Beacon control panel):
  Navigate to the plugin installer, search for spark, and click install.

• Manual upload:

  1. Download Spark from https://www.spigotmc.org/resources/spark.57242/
  2. Upload the .jar file to your server’s /plugins directory via the File Manager or sFTP.

Step 4: Run the Spark Profiler

To begin profiling, run the following command from the in-game chat (as an OP) or the server console:

/spark profiler --timeout 60

This will record 60 seconds of server performance data.

Once completed, Spark will return a URL to your profiling report. You can open this in your browser to review a detailed breakdown of:

• Tick timings
• CPU usage
• Plugin impact
• Thread activity
