About this Modpack
📢Declare
Relentleserver is designed for server use and unsuitable for client use. If you aim to enhance your game performance, I recommend using my client-side performance modpack, Arcomua Modpack, which can greatly improve the framerate and other aspects of gameplay.
📎Introduction
Relentleserver is a performance-focused serverpack that also includes management mods for server use. It is designed to quickly build servers with management features and good performance without changing the core gameplay.

Frequently Asked Questions
Relentleserver 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.

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 Relentleserver 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.
Relentleserver 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.
