Mod spark

Spark Minecraft performance mod

Spark is a powerful performance profiler for Minecraft that helps you analyze what really causes lag on your Minecraft server or client. It records CPU usage, tick times and memory behavior, then generates detailed online reports so you can see exactly which worlds, plugins or mods are slowing things down. Compatible with many versions of Minecraft and major mod loaders, it is lightweight enough for production environments.

We use Spark on our Minecraft server infrastructure at BoxToPlay to monitor TPS, diagnose spikes and keep worlds smooth for players, especially on larger modpacks or complex survival worlds.
