The main focus of this project is to provide an easy, ready-to-use, optimized FML-based modpack for creators.

🔬 Insights...

‎

⏫ Automatic maintenance

FML Optimized has been designed for its mods and configs to just be grabbed and thrown into your modpacks. And thanks to our automatic maintenance (Provided by Mods Optimizer) you can even apply a new version of FML Optimized to an already existing modpack with no need to worry about old mod files piling up, we'll take care of them.

With FML Optimized, you also do not need to have separate versions for the CLIENT and SERVER, instead the modpack will automatically adjust itself for the correct environment.

📑 Precaution info

⚠️ This section contains known incompatibilities and mods you should treat with caution

Adding Smooth Chunk Save will slow down chunk generation speeds by around 20%.
Acedium, Palladium, and Flerovium unfortunately couldn't make it into the final modpack due to the mods likely causing issues with large modpacks.
ServerCore is included by default for the performance benefits. But if you're experiencing issues with mob spawning, then you should try removing this mod. In the past, ServerCore has had some issues with this.

We recommend checking out the Fabric side if you're looking for an experience tailored more for personal every-day use. (Or if you need a template for your Fabric projects.) Start here...

Frequently Asked Questions

FML Optimized server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong neoforge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a FML Optimized server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).

Can I add custom mods to FML Optimized without conflicts?

Yes, but check compatibility: only use mods for the same loader (neoforge) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

FML Optimized server lagging – performance tips

1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
