We had a long, drawn out support ticket with Unifi about this. In the end they said this incredibly high CPU usage was expected behaviour banghead Much of the saga is chronicled here: https://community.ui.com/questions/...CPU/ca8d4f20-ec87-4c38-aa04-33ac05f1fb2f

It turned out our workaround of /usr/bin/cpulimit -b -l 50 -e /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java caused a few other issues such as occasional controller lockups and lack of client stats when viewing a site. (black screen when trying to view client device list)

This morning we upgraded the controller software to 6.5.53 and happened to notice an option to turn off "Analytics & Improvements" under Network Application>Console Settings. The Unifi upgrade didn't make much of a change even after we gave the CPU a chance to settle down. However, within minutes of turning off "Analytics & Improvements" our CPU usage on the AWS t3a.xlarge instance went from around 45% to 2.5% and has been there for a half hour! We may be jumping the gun but this option appears to be the single source of all the nasty Java CPU usage.

"...they said this incredibly high CPU usage was expected behaviour."

If that is the case, then it is definitely an Engineering Oversight. No excuse for resources to be tied up!
