About this Modpack

Lrbium (aka lebium)

small inside joke between my friends

this modpack keeps core gameplay like vanilla while adding a lot of performance features, some Bug Fixes and Quality of Life features without trying to reduce performance

this modpack (in theory) should be compatible with vanilla servers and allow vanilla players to join if you host a server with this modpack

What this modpack will add

for example

c2me really awesome chunk performance mod that optimizes chunk loading
zoomify really awesome zoom mod

These mods don't modify core gameplay (see below), but do add Quality of Life and performance improvements, and generally don't impact performance

What this modpack wont add

for example

tom's simple storage
Wavey Capes While this doesnt modify gameplay, it does have a slight performance impact

Mods like these will not be added since it modifies core gameplay, or impacts performance (i'm not saying these are bad mods)

Frequently Asked Questions

Lrbium 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 Lrbium 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 Lrbium without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.3). 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.

Lrbium 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.
