Hello,

When you use python in a parameter it's not only ran once when the node updates in any capacity but multiple times. This becomes even worse if you use python in a multi parm as this causes the python parm to evaluate exponentially.

I don't know if this is a long time bug or an uncontrollable aspect of how nodes evaluate. I try to avoid using Python in general in parms but sometimes it's necessary. So I was wondering if anyone knows if there's a work around to get these python parms not to run inefficiently or if this is just how it's unfortunately got to work?

Thanks

Updating UI elements like the parameter pane is the most likely culprit. Have you tried hiding UI elements and see if it helps?
