Grouper Users - Open Discussion List

[Shilen Patel <>]

Just to give you an idea, in the Fall when Duke loaded its Spring  
courses, the initial load took 65 minutes.  That load added course  
data for 7045 courses, which for us translates to 21,135 groups,  
approximately 21,135 stems, approximately 100,000 privileges for the  
groups and stems, and an unknown number of student and instructor  
memberships.
