            Bug ID: 107945
           Summary: Performance of pivot table cache population can be
                    improved...
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: kohei.yoshida at collabora.com

Description:
We have a customer document (xlsx file) that exhibits a slow import.  Upon
further examination at least a part of the poor performance stems from pivot
cache population esp. in

ScDPCache::InitFromDoc(...)

where we are not properly parsing the column values using the
multi_type_vector's position iterators.

We should be able to improve the performance of this code, and I'm currently
looking into this.
