           Summary: Performance problem with large models
           Product: umbrello
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: okellogg users sourceforge net


Version:            (using KDE Devel)
Installed from:    Compiled sources

Loading a model containing the main classes of ACE (http://www.cs.wustl.edu/~schmidt/ACE_wrappers/ace/) takes in excess of 20 minutes on a 1GHz Pentium Linux machine.
This is due to the new xmi.id resolution pass which was added for loading foreign XMI files.
We should look into how to make type resolution scale well (e.g. use a dictionary of pointers to unresolved references which is indexed by xmi.id instead of the current linear search.)
