I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Overview
SyncBoost optimizes meaningless server-side hopper polling when idle. Container GUI synchronization is left entirely to vanilla to ensure gameplay correctness.
Core Strategy (Delivery Safe Version)
- Container Sync: Does not intercept
sendContentUpdates(), avoiding revision / property / cursor protocol risks - Hopper Idle Skip: Only skips 2 ticks when ALL of the following are met:
- Server-side
- Hopper not on cooldown (
transferCooldown == 0/ Mojang:cooldownTime == 0) - Hopper itself is empty
- An Inventory / Container exists directly above
- Content hash of the above Inventory has not changed
- Cross-Dimension Isolation: Tracking key includes dimension hash to prevent same-coordinate crosstalk
What It Does NOT Do
- Does not rewrite container network synchronization
- Does not skip item pickup path (passes through to vanilla when no container above)
- Does not modify hopper cooldown semantics
