      Our Jenkins server was on 100% CPU usage.
      4 threads were very busy with sending an email.
      All 4 thread had the same stacktrace, see screenshot.

      Looks like that lookup of emailadresses is consuming too much CPU.

          E-mail address revolvers are other plugins, the email-ext plugin just uses the core Jenkins address revolver functionality so I'm not sure how to handle this issue in the plugin itself.

          If this is an API of Jenkins Core, then you might transfer it to Core.

          When will this API be used? In all situations or when certains settings are done for sending the email?

          It will be used when a user's email address needs to be resolved.

          1) Do you use svn?
          2) what svn plugin version?
          3) what jenkins version?
          4) what email-ext version?
          5) Can you paste thread dump as text here?
          6) How long email is sending?
          I post my small debug story to #JENKINS-14285 maybe it helps you.
