Redstonecompiler

Vanilla redstone recalculates each wire and repeater separately on every update, so a large circuit can take milliseconds per tick and slow the whole server. Redstonecompiler replaces that flow for supported circuits: it generates a Java class at runtime with ASM, compiles the circuit's logic into native code, and lets the JVM's JIT compiler optimize the result. The compiled circuit is then evaluated through a single method call.

The mod covers redstone wire, repeaters, comparators and logic operations, including comparator COMPARE and SUBTRACT modes, logic inversion and GreaterThan logic. Repeater delay stays at one tick per stage, so the timing of signal propagation is preserved. Small circuits gain little, since compilation overhead roughly cancels out the speedup, so the largest benefit appears in mega-builds such as multi-bit ALUs and auto-sorters. Fabric API is required, and Cloth Config API and Mod Menu are optional.
