    Default CPU Consume is High process Jetty

    Good morning, my server's CPU consumes too many resources and makes access to Web Mail is too slow, I checked the server processes and the process that consumes too many resources is the jetty.

    You should give details of your hardware specification and how many users are on the server (and whether they're IMAP or web UI clients), you should also consider upgrading to the most recent Zimbra release.
