Divide the list in half (or quarters, or 8ths… 256ths if you would like) and run portions of the script on multiple systems using different user names on each one.
Or… and this is pure insanity… and it’s really risky… maybe I shouldn’t build this atom bomb… but… one could open multiple revit sessions on the same system each with a different user name, and then open the same dynamo graph, and run the first half (quarter, 8th, 256th) on one session, and the other on the next session, and so on…
If you do this please post a screenshot of your task manager’s performance page so i can go “oooooooo” and “aaaahhhhhh” for a few hours…
