Did this mod make your server playable? Chip in a bit of money so I can continue developing it.

What's Krypton?

Krypton (from Ancient Greek kryptos, "the hidden one") is a Fabric mod that attempts to optimize the Minecraft networking stack. It derives from work done in the Velocity and Tuinity projects.

Krypton contains several optimizations, including:

Highly optimized Netty handlers derived from the Velocity proxy, which I am the developer of. These handlers have sen 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.
