https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/installation-requirements has some numbers.

We know of Fleet deployments with thousands of clusters. However, it depends on your workloads, too. If you deploy 600 gitrepos with dozens of large (in terms of manifest size) apps to 1000 clusters, that's different than deploying some paths of 10 gitrepos to a set of the 1000 clusters.
If your repos change once a month and reaction time should be within minutes, that's different from frequently changing repos you want to roll out within seconds.
