Summary: Updating bugs with lots of CCs take far too long
           Product: WineHQ Bugzilla
           Version: 3.2.3
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: source
          Severity: trivial
          Priority: P4
         Component: bugzilla-unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I'm sure anyone who has been using Bugzilla for long enough has noticed that
updating bugs with a large number of CCs and/or votes takes unreasonably long.
Marking a bug a duplicate of another can time out.

You can ignore this by reopening the bug without waiting for the page to
reload, and the emails will still be sent.

Can something be changed for this?  We don't really need to know who is being
emailed, it can be assumed from the lists.
