I'm not the jenkins admin of this instance, so I'm limited to what I can do   However, we use the robot plugin to report on test results.  Recently, we had some builds fail a lot of the test suites (39 suites, 35 ish fails each run).  Loading the /robot page for one of these takes between a minute to a minute and a half.  My best guess is that is' due to the large number of fails - the build immediately prior to the fails starting (and normal useage) is that it takes at worst a few seconds to load.  CPU is apparently jumping to 110% while it happens.  Is there anything I can gather (as a user) that would help, or do I need to ask the admins to get any data?
