====32. Speeding it Up with the Performance Monitor====
Dialogs -> [[Performance Monitor]] will let you see, in one frame, what nodes cook, in what order, and how long they took. Nw be aware, Performance Monitor only shows what cooks on the CPU, not the GPU. But a long bar at the bottom usually means the GPU is still busy finishing rendering a frame and displaying the UI. 

middle-click on any node to see if the node is cooking every frame or not, and how long it took the most recent time it cooked.

There is also the Perform CHOP, and you can create Info CHOP and drag any node onto it  to see more detail on what happened.

And there is in the palette: Palette -> Tools -> probe, and a wiki page on it: [[Palette:Probe]].
