From what support tells me 20 installs per minute limits any software deployment to small batches. Aside from the limit, the network potentially chokes up at the internet line. These are limits that need/can be managed. For example... determine if the software is already installed, and if not, determine the number of IP addresses receiving the request, round robin downloads by randomization of a delay between 1 - 15 minutes and peer to peer share the downloaded file for deployment or designate an agent download point inside the network as preferred method if available.
