How to Optimize Your Modded Server on HolyHosting 🔧

Minecraft·March 22, 2026·17 min read


Hello👋!! Today we bring you a tutorial on how to optimize your modded server on HolyHosting, your trusted hosting provider. Optimizing a modded server is easy thanks to the large number of optimization mods available.

Optimization mods can be synchronous or asynchronous. Synchronous ones use the same thread as Minecraft, while asynchronous ones use different threads, which improves performance.

Common Problem⚠️:

  • Error: Using too many synchronous mods on a server with low RAM.
  • Solution: Implement asynchronous mods and increase the available RAM.

RAM is crucial for keeping an optimized server. If there's low RAM, threads are negatively affected, causing processes to slow down and become unstable.

Common Problem⚠️:

  • Error: The server runs out of RAM, causing lag.
  • Solution: Increase the server's RAM and optimize mod usage so they don't consume too many resources.

Before optimizing, we need to identify the cause of lag. Use a mod like Spark to monitor the server. Run the command /spark profiler to create a link that will let you view processes and their resource consumption.

Common Problem⚠️:

  • Error: Not being able to identify the exact process causing lag.
  • Solution: Use monitoring tools like Spark and analyze the resource usage graphs to detect problems.

Here are five essential mods to optimize your server, whether Forge or Fabric:

  1. AI Reducer: Reduces the load caused by entity artificial intelligence.
  2. Chunk-Pregeneration: Pre-loads chunks to avoid generating them in real time.
  3. MemoryFix: Optimizes RAM usage.
  4. LagGoggles: Fixes bugs and optimizes processes.
  5. ServerCore: Optimizes your server as if it were a plugin server.

Common Problem⚠️:

  • Error: Incompatibility between mods.
  • Solution: Verify mod compatibility before installing them and remove those that cause conflicts.

Shut down your server and enter the ServerCore configuration. Use the dynamic optimization option to adjust settings in real time based on the server's state ⏰.

Common Problem⚠️:

  • Error: Incorrect settings that cause more lag.
  • Solution: Enable dynamic optimization and only adjust what you understand.

To pre-load chunks, start your server and use Chunky. Set the center at your spawn and select the chunk radius to pre-load.

Common Problem⚠️:

  • Error: Pre-loading too many chunks and exhausting resources.
  • Solution: Pre-load chunks in smaller batches and monitor resource usage.
