Issue seems to be related to to AbstractLazyLoadRunMap blocking when categorised view is used. This is causing Jenkins to backup while waiting for unblock. Causing page load times to slow down.

      Cause on last line.

      To reproduce:

      • 100+ build history
      • Slow Disk (not sure how to apply this to a test at the moment)

      Plugin: categorized-view:1.8
      Jenkins: 1.609

          The issue report does not contain enough information to determine what the bug is, or whether it is indeed a bug. The stack trace in question loads a single build (the latest one) for a job. If your disk is so slow, there's something seriously wrong with your setup.

          Also, 1.609.4.6 is not a Jenkins version. This needs to happen with an actual Jenkins release for anyone on this tracker to care.
