Channels... How and When

Yes @wizard, thanks so much! As always, complete, generous, fantastic and wizardly.

I dug this up from an older thread -

The buffered neopixel designation in setup is not available in the V3 front end. That designation makes things run much faster on the V2 at least. Is there a reason for this?

I’m assuming that with computationally intensive code things slow down (?)

Thanks again!
