n-Command Capacity

[Gods_Youngan]

I need to push a new firmware to 2,000ish routers. I have been pushing it out in a block of 50 every hour. Could I push at a rate of 50 every :30min without overtasking the server. What is the recommended pace or capacity for large blocks of firmware pushes ?

I see a max count at 100 but not sure how often I can push a batch of 100.
