Grouper maintains subject ids in the grouper_members table. It is up to the 
source adapter to map the subject id to a uuid in the IDM/ID Store.

Duke, Brown, Cornell and others probably have direct experience, but 
generating lots of new groups and/or memberships will take some time 8hrs+ 
I would guess depending on your systems and the numbers involved

There is no limit as such - assuming your RDBMS can hold the data and 
indexes. Depending on how groups are structured in a stem hierarchy and how 
privileges are assigned some operations, particularly in the UI, may be 
slow.

I believe sites are using 100,000s of groups and millions of memberships.
