About this Modpack

I forgot about this, do you believe it?

The modpack description will be moderately modified during the month

I think this profile is just too unpretty

This modpack brings a performance boost to the game

It does this without changing the in-game graphical user interface (GUI) and game content

Feature introduction Use Async Pack Scan to speed up the loading of resource packs
Use C²ME (Fabric) (Concurrent Chunk Management Engine (Fabric) ) to optimize block-related performance
Use FPS Reducer to reduce the performance footprint when the game is in the background
Optimize memory usage with FerriteCore
Use ImmediatelyFast to improve Instant Mode rendering performance
Use Indium to provide a rendering API so that mods that use the Fabric Rendering API work at the same time as Sodium
Use Iris Shaders to provide light and shadow loading so that people who don't know how to use light and shadow loaders don't mess around online and don't use search engines
Use Language Reload to optimize the speed of in-game language switching, and support multi-language selection and multi-language search
Use LazyDFU to speed up the game's startup (although MOJANG has significantly optimized DFU since 1.19.4, I still added this mod to the modpack to prevent MOJANG from doing bad optimizations in this area as before)
Use Lithium to optimize the game system, but not change the game mechanics (although I feel that this passage is weird, but it is the author's exact words).
Use the Mod Menu to help players view mods as well as change mod configurations
Port bug fixes, optimize and improve the game's startup with ModernFix to improve speed and reduce crashes, optimize memory usage
Speed up rendering with Noxesium
Use Sodium to improve rendering performance and fix some graphics issues
Use Sodium Extra to add most of the features of Optify to the Sodium
Use Starlight (Fabric) to improve lighting performance and fix lighting bugs (although MOJANG has significantly improved lighting since 1.20, I still added this mod to the mod pack to prevent MOJANG from doing the same negative optimization in this area as it has in the past) (this may be redundant).
Use ThreadTweak to improve and adjust CPU thread scheduling
Use fast-ip-ping to speed up server pings
The main focus of this modpack is to optimize the performance of the game, and it does this by not adding any unnecessary extra features, thus ensuring that it remains very lightweight
This modpack has a backup repository on Github, and you can create an issue if you have any questions (I wouldn't say it's open source because I don't do anything other than integration).
Compared to Optifine, this modpack is more compatible with other mods without errors or missing textures, tearing, or crashes
When the modpack is not installed on the server, the client will still be able to play on the server and will not change any game content
This modpack keeps up with the latest version of the game (and of course I have to note that there are new versions).
This modpack is very lightweight, for example, after installing version 1.0.1, it only takes up 19.0 MB of storage
So, get ready to get the best gaming experience by improving performance and efficiency!
Another point, because I am not good at English, I used Microsoft Translator to write the above words, and I am very sorry if it has caused you inconvenience or misunderstanding.
If you can help me translate, I would appreciate it.

How to Set Up a Only Optimized Server

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

Frequently Asked Questions

Only Optimized 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 Only Optimized server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 5 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 Only Optimized without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). 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.

Only Optimized 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.
