Where the load comes from

Event hooks carry 99.8% of this mod's structural load. 0.001 ms/s in all.

Counts how often each hook is dispatched and how many timers stay alive, not what the code inside does. Some rates are order-of-magnitude estimates; the methodology lists which.

Where this mod runs often

Hooks on per-frame and high-rate surfaces, with what their bodies call. Body work, not the hook itself, is what costs frame time.

Other findings

What this report can tell you

Which vanilla methods the mod hooks, which of them drop the chain, how often each hook fires, and which risky calls sit inside hot hooks.

What it cannot

How long hook bodies take, network cost, or engine-side load. Measured across live fleets, most server lag comes from the engine and world state, not mod script chains — a light footprint does not clear a mod of lag, and a heavy one does not convict it. Methodology.

Everything else

All 39 overrides

Surface is the dispatch tier the rubric can price (— = unpriced); server is whether the override exists on a dedicated server; super() shows whether the vanilla chain is preserved on a server.
