How to Host a Keo Optimized Server (Fabric Performance Setup Guide)
Keo Optimized is a lightweight Fabric pack built around one goal: higher FPS without changing how vanilla Minecraft plays. Hosting it right is simpler than almost any modpack — a modest RAM floor, a quick first boot, and no large content systems to worry about. Here's how to get a Keo Optimized server running without wasting resources it doesn't need.
Start with at least 4GB of RAM dedicated to the modpack. Keo Optimized is built to be lightweight by design — it ships only essential Fabric performance mods, so it doesn't need the 8-10GB floor a content-heavy pack would, and over-provisioning here just goes unused.
Import the official server pack directly through CoalHost's panel. Even a small, focused mod list like this one benefits from the real server pack over a hand-built mod folder — it guarantees every performance mod is on the exact version the pack author tested.
Watch the first boot, which should be fast — there's no large content system to register, just a handful of optimization mods loading on top of vanilla. A boot that drags here is a more useful warning sign than on a 500-mod kitchen-sink pack, precisely because there's so little that should slow it down.
Open the server to players as soon as that quick first boot completes cleanly. Because Keo Optimized doesn't add new content, blocks, or structures, there's little risk in players exploring immediately — the mods here only change how the game runs, not what's in the world.
Still take a backup before any mod or Fabric update, even on a pack this light. Performance mods occasionally change world-saving behavior, and a backup costs nothing to keep on hand.
Use a cleaner Keo Optimized path
CoalHost is built around modpack hosting, which makes Keo Optimized much less annoying to launch correctly.
