AdvisorThe python script that builds the dynamic groups shouldn't have any impact unless you're running it on the collector. It makes a few GETs to find out what is present already and makes 1 call to create the parent group (if it doesn't already exist), 1 call per collector group to create the collector group groups, and 1 call per collector to create the collector group. So, if you have 30 collectors across 3 groups, it makes up to 34 API calls.
The DS makes one API call for discovery and one for collection.
All told, they should both be pretty lightweight.
