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.

Getting to Know Optimization Mods 🛠️

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.

Importance of RAM and Threads 🧠

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.

Identifying the Cause of Lag 🐢

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.

ServerCore Configuration ⚙️

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.

Pre-loading Chunks with Chunky 📦

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.
