OcelotPack

Forget about "doubling" your FPS. We can do better.

This is a Minecraft modpack on Fabric, focusing on optimisation, customisation and stability. The goal is not to have any opinionated stuff here. This could just as well be vanilla.
Inspired by Fabulously Optimized and the OptiFine alternatives by LambdAurora.

Frequently Asked Questions

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

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 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 OcelotPack server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 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 €8/month).

Can I add custom mods to OcelotPack without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) 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.

OcelotPack server lagging – performance tips

1) Increase RAM to 6 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.
