Paste a spark.lucko.me link and get straight answers: what is eating your server's ticks, which chunks, plugins or mods are behind it, and exactly what to change (or which optimization mod to add) for your kind of server.
/spark profiler, /spark heapsummary or /spark health.Reads the profiler and breaks your tick time down by area: entities, chunks, redstone, hoppers, lighting and more.
Detects Paper / Fabric / Forge / NeoForge and recommends the right optimization mod for the exact problem (Lithium, Canary, Moonrise, C2ME, FerriteCore…).
Lists the worst chunks by entity count, with coordinates, so you can jump right to the lag. Packed chunks are the number one cause.
Ranks plugins/mods by their share of server-thread time, so a single heavy add-on can't hide.
TPS, MSPT, CPU, memory, GC and world stats with red / yellow / green status at a glance.
Interactive flame graph + call tree, heap class histogram, and per-minute TPS/MSPT/CPU history.
