FluidCore

FluidCore is a lightweight Fabric performance mod that
optimizes Minecraft's vanilla fluid tick system for both
singleplayer and multiplayer servers.

How It Works

Vanilla Minecraft ticks every single water and lava block
every few game ticks — even blocks that haven't changed in
minutes, and even when no player is nearby. FluidCore
introduces a smart sleep/wake system that eliminates this
wasted CPU time.

• Distance-based sleeping — Fluid blocks farther than
  96 blocks from any player are put to sleep and stop ticking
• Stability counter — Fluid blocks that haven't changed
  for 60 ticks are gradually put to sleep, even near players
• Event-driven wake-up — Sleeping fluids instantly wake
  up when a nearby block changes, ensuring correct behavior
• Chunk unload cleanup — Sleeping fluid data is
  automatically cleaned when chunks unload, preventing memory
  leaks
• Both source and flowing blocks — Optimizes both water/
  lava source blocks and flowing blocks
