Twenty or Less Mods Performance
I attempt to keep a modpack to one page of a list that focuses on client side optimization mods.
About this Modpack
While I was actually working on the modpack "Fabric Bare Performance", I basically realized that probably partially due to an increase of optimization mods in later versions, they can get progressively unstable and may not even contribute to FPS increase as much as they may imply.
This being the case, I'll start down from 1.14.2 and go back up for parity's sake and slowly experiment what works best with what I have that's available. Maybe I already did it, and this part of the description is an afterthought, but regardless that is basically the method I will go about in making this modpack for this instance: to make it at a constant amount and a challenge to keep the modpack "lighter" than the original iteration of what I worked on.
The standard I'll do for testing pretty much is keep everything at standard settings as minecraft would launch from, with the exception of Unlimited FPS in case the frames exceed those speeds (although let's be honest, my laptop would barely like to reach those high frame rates anyway pffffft). Other things I'm keeping constant is same world seed, and staying still with the world already loaded since FPS will naturally fluctuate depending on where you are and what you're doing.
Also since I'll be focusing on FPS instead of QoL performance stuffs individually, I'll put down my Vanilla FPS vs Modded FPS for comparison given how everyone has different systems. And since it'll be among different versions, I'll just do an average per main version (like 1.18, 1.17, 1.16, etc.) on the description page, and for per changelog I'll put down the specific average FPS comparison.
Addendum: It's come to my attention as I was dabbling in 1.17 that there are mods out there that won't optimize FPS, but will most certainly prevent more lag should a specific scenario come along like a lot of chests or a lot of redstone. Mods that selectively tackle these issues that aren't always ever present has led me to decide to make "Honorable Mention" versions of modpacks-they are technally 20 mods focused on performance, but with added mods that tackle particular situations. In some ways it could even argue that this is the better modpack to download, but to each their own I've decided to commit to this challenge regardless as this is a modpack aimed at overall performance.
1.14. Current Verdict: Most of the optimization mods that exist here do not act to improve FPS, but actally to stabilize and fix issues-either go Vanilla or use Optifine if you want more ideal FPS increases. Biggest exception right now is 1.14.4 where it's basically break even between frame rates.
- Vanilla: 110~ FPS
- Modpack: 100~ FPS
1.15. Current Verdict: The mods in use technically speaking don't reach the same peaks as true vanilla, however they they do mostly appear more stable and consistent which I'd say is nice.
- Vanilla: 100~ FPS
- Modpack: 100~ FPS
1.16. Current Verdict: There's enough mods here and their associated effects to warrant using them for sure. With it also being 1.16 there's naturally more things to generate and load so vanilla performance goes down a bit.
- Vanilla: 95~ FPS
- Modpack: 105~ FPS
1.17. Current Verdict: WIP
- Vanilla: WIP
- Modpack: WIP
1.18. Current Verdict: WIP
- Vanilla: WIP
- Modpack: WIP
1.!9. Current Verdict: WIP
- Vanilla: WIP
- Modpack: WIP
1.20. Current Verdict: WIP
- Vanilla: WIP
- Modpack: WIP
1.21. Current Verdict: WIP
- Vanilla: WIP
- Modpack: WIP

Frequently Asked Questions
Twenty or Less Mods Performance 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 Twenty or Less Mods Performance 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 Twenty or Less Mods Performance without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.17). 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.
Twenty or Less Mods Performance 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.
