    • Jenkins 2.0

      I'm using the official docker image, no customisation.
      After the update to the 2.0, the Jenkins CPU usage has increased from near 2% to 40%.
      I get CPU spikes navigating the UI for example in http://<JENKINS_ENDPOINT>/configure, the scheduled job seems not to have this behaviours.

          Some of the new UI will definitely use more CPU on the client side, I don't think this is critical or a regression, but rather an expected byproduct of increased rich client UI.

          I'm running Jenkins master on a t2.small instance the CPU usage is consuming all the instance credits. The new UI is nicer than the old one but spikes of 40%of CPU for the configure page seems not right on my end.

          ltagliamonte have you compared this to the previous 1.x release? The code actually rendering the page on the server side doesn't have significant changes as far as I know. What plugins do you have installed?

          I've got the same problem, the jenkins UI (2.26) is pegging 100% of a CPU, while completely idle.

           

          A simple CPU profile in Chrome show's 99% of time is spent in Timer-Fired, indicating there's some wild timer abuse happening on the page.

           

           

          This is seriously bad, I can't open the Jenkins UI without my laptop fans blazing.

          We have been experiencing some high CPU issue on our jenkins server for quite a while. Among all the running thread, one of the jenkins.util.Timer thread consumes high CPU usage. There are 10 jenkins.util.Timer thread running, the rest 9 thread consume less than 1% CPU. Anyone has any idea about this?
