setting the right z-wave parameters

Can anyone please point me to an article or forum post that makes certain recommendations when you have 50+ z-wave devices connected to 1 vera. I am mainly concerned about polling times, how are these tweaked based on deployment size?

Other than having good routes by performing at least 3 heals “repair my network” I don’t know of any other settings (from default) or secret sauce that would make an improvement.

You could turn off polling “0” to any battery operated devices and Leviton controllers but I doubt you will see any difference.
