About this Modpack

Just something I wanted to put together. This might not be the optimal combination for optimization, but I did my best based on wanting to get the best experience without necessarily changing anything critical about the game or creating any major tradeoffs. You should be able to use this set of mods on top of many other mods, be they content mods or other optimization mods. (Although I should say that InstantlyFast seemed to have some conflicts so I opted to not include it here. If you know more about this kinda stuff and want to make changes to include InstantlyFast, be my guest. This modpack was made with the idea of being a baseplate that you can build off of. Theoretically this is compatible with most other mods.)

I don't know what I'm doing, so here's the list of mods if you want to just start it manually, just in case I'm stupid and did something wrong lol

How to Set Up a Pure Optimization Server

Order Server

Choose at least 4 GB RAM (6 GB recommended for Pure Optimization). Based on player count: per 8 players.

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "Pure Optimization" and click "Install". The fabric loader and Minecraft 1.21.5 are configured automatically.

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

Pure Optimization 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 Pure Optimization 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 Pure Optimization without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.5). 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.

Pure Optimization 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.
