KryptonFoxified
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.

What's Krypton Foxified?
Krypton Foxified is a NeoForge mod that attempts to optimize the Minecraft networking stack. It derives from work done in the Velocity and Tuinity projects.
Krypton Foxified contains several optimizations, including:
- Highly optimized Netty handlers derived from the Velocity proxy, which I am the developer of. These handlers have seen real-world usage and extensive profiling, and strategically deploy native code where it makes the most sense.
- Flush consolidation to lower server CPU usage (and reducing the impact from hardware security vulnerabilities which exploit speculative execution) and lower server tick times.
- Micro-optimizations to reduce memory usage and improve packet serialization speeds.
Compatibility
Krypton Foxified should work anywhere where a Minecraft can run.
