Nitroserver
Lightweight serverside optimizations for Fabric 1.20.1, 1.20.6 and 1.21
About this Modpack


Performance is the priority
Nitroserver is based on making performance as good as possible, on a serverside level whilst allowing vanilla clients to join. It utilizes mods such as Lithium, Krypton, Noisium, ServerCore and C2ME to speed up the serverside operations.
Generally, Nitroserver will outperform other modpacks of its kind whilst updating quicker and adapting faster.
Nitroserver maintains 100% vanilla parity, however it optimizes the server in the following areas:
- Chunk load times decreased by ~70-90% via Noisium and C2ME
- Memory usage decreased via FerriteCore and ModernFix
- Entity spawning and fluid optimizations which makes the game run faster and more stably
- Serverside logic optimizations that make entities run better, lag less and improve performance
- Lighting engine optimizations
Nitroserver also includes only Open Source or Source Visible mods. Feel free to contribute to them all.

Frequently Asked Questions
Nitroserver 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 Nitroserver 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 Nitroserver without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). 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.
Nitroserver 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.
