Plugin spark

spark Nukkit performance profiler

spark is a performance profiling plugin for a Nukkit based Minecraft server. Built from the wider spark project, it helps administrators investigate lag, low tick rates, high processor usage, memory pressure, and unstable server behavior. The Nukkit release belongs to spark’s extra platform implementations, so it is community supported and may not receive the same support level as the main releases.

It combines a lightweight CPU profiler with memory inspection and server health reporting. Owners can review TPS, tick durations, processor and memory usage, garbage collection activity, and detailed profiling data to locate expensive tasks or diagnose recurring slowdowns. At BoxToPlay, it is a practical observability tool for keeping a busy Minecraft server responsive.
