Minecraft server performance issues, specifically low ticks per second (TPS), can significantly impact gameplay. This guide addresses a common scenario: low TPS coupled with low CPU usage and high millisecond per tick (MSPT). This indicates the problem isn't necessarily a lack of processing power, but rather inefficient resource management within the server environment.

Identifying the Root Cause

The combination of low TPS, low CPU usage, and high MSPT suggests that the server is spending excessive time on tasks other than processing game ticks. This often points to issues within the server's plugins, world generation, or even network congestion. Let's explore the most common culprits:

1. Inefficient or Buggy Plugins

• The Problem: Poorly coded or resource-intensive plugins are frequent offenders. A single poorly optimized plugin can severely bottleneck the entire server.
• Troubleshooting Steps:
  • Disable Plugins One by One: Temporarily disable plugins systematically to pinpoint the culprit. Monitor TPS after each deactivation. The plugin causing the issue will often result in a significant TPS increase upon its removal.
  • Plugin Updates: Ensure all your plugins are up-to-date. Older versions may contain bugs or inefficiencies.
  • Plugin Alternatives: Consider replacing resource-heavy plugins with lighter alternatives that offer similar functionality.

2. World Generation Issues

• The Problem: Large, complex worlds, particularly those with excessive entities or extensive redstone contraptions, can strain server resources. Chunk loading issues can also contribute to low TPS.
• Troubleshooting Steps:
  • Check for Lag Spikes: Observe if TPS drops coincide with players entering specific areas of the world. This might highlight problem regions.
  • Optimize World Generation: If possible, consider generating a new world with improved settings or use world border optimization techniques to minimize the loaded area.
  • Entity Count: High entity counts (mobs, items, etc.) drastically impact performance. Utilize plugins or commands to reduce the number of entities.

3. Network Congestion

• The Problem: High network latency, especially if many players are experiencing high ping, can indirectly lead to low TPS. The server spends time waiting for responses from clients.
• Troubleshooting Steps:
  • Check Network Bandwidth: Verify your server's network connection has sufficient upload and download speed to handle the number of players.
  • Player Location: If the issue only occurs during peak hours, high concurrent player access might overwhelm the network. Consider upgrading server hardware or network bandwidth.
  • Server Location: The server's physical location can influence network latency for players in different regions.

4. Server Hardware Limitations

• The Problem: While low CPU usage might seem to rule this out, other hardware limitations like insufficient RAM can still bottleneck the server. The server might be waiting for resources even if the CPU is not fully utilized.
• Troubleshooting Steps:
  • Monitor RAM Usage: Ensure the server has enough RAM allocated. Increase RAM allocation if necessary.
  • Check Disk I/O: Slow hard drives can cause significant lag. Consider upgrading to an SSD.

Further Investigation and Solutions

If the above steps don't resolve the issue, consider these additional steps:

• Forge Version Compatibility: Ensure your Forge version is compatible with all your plugins and the Minecraft version.
• Server Logs: Analyze your server logs for error messages or warnings that might provide clues about the problem.
• Forge Support: Consult the Forge support forums or documentation for additional troubleshooting tips.
• Professional Support: If all else fails, seeking professional help from experienced Minecraft server administrators might be necessary.

By systematically addressing these potential causes, you can identify and resolve the root cause of your low TPS issues, restoring optimal performance to your Minecraft Forge server. Remember to always back up your server before making significant changes.
