I've been watching the Jamf Pro 10 threads (there's a lot fewer than I thought there would be). I don't have a formal test environment so my own testing is pretty limited. I haven't seen anything that would be production halting. Some performance teething pains sure, and I expect there to be things like that with an overhaul such as this.
We have about 1,000 devices, spread out. I'm the only one in the web GUI, but IT staff all over the US and overseas access imaging and remote. The infrastructure is setup on 2013 Mac pro's - one for jss / memcached and one for mysql, and then a mix of mini's and Mac pros across the major sites for distribution points.
