It seems as if the more APs we add and the more clients join our network, the slower the dashboard gets. (We have about 900 APs with 20k active clients) The problem is most noticeable in the clients view. What was just a minor annoyance a few years ago has turned in to a major problem. Searching for clients has become extremely difficult, even on the short timescale of 2 hours. It'll say "Loading..." for a minute or two and then usually time out with the message "We were unable to load the clients in this network. Try searching for a particular client." We frequently need to use the clients view, but it is basically unusable for us.
I've had a couple cases open with support for this issue going back 2 years. I've been on the waiting list for engineering to look at this issue for months.
I was wondering, has anyone else here has had a similar experience? If so, how did you resolve it?
