            Bug ID: 131204
           Summary: Exceptionally slow SORTING
           Product: LibreOffice
           Version: 6.3.5.2 release
          Hardware: x86-64 (AMD64)
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: that.man.colin at gmail.com

Description:

A sheet with 416 rows 37 columns containing mostly numerical data of two digits
custom sorting on an alpha column of 3 digits takes substantially longer
following the update - it's almost comparable with watching paint dry.
Fifteen of the numerical columns are the result of minor formulae and the 3
character alpha column being sorted is also formula driven

Steps to Reproduce:
1.Using sheet "All Hits from the attached file EJResults.ods
2.Select data from A11 to bottom of column AK (Select the first two rows and
then select to end of range with CTRL + SHIFT + Down)
3.Select sort button
4.Sort on Column L with option Custom sort order
5.The custom sort is the final table - scroll down to the bottom of the list
6.Allow it to sort



Actual Results:
Takes many times longer with the update today then previously

Expected Results:
Faster sort - comparable to the previous release


Reproducible: Always


User Profile Reset: No
