            Bug ID: 116844
           Summary: PERFORMANCE - Opening 11Mb Calc sheet takes 14 minutes
                    in LO, 2 minutes in Excel
           Product: LibreOffice
           Version: 6.0.3.2 release
          Hardware: All
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Opening the enclosed ODS file in a variety of apps on macOS 10.13.4.

Performance with LO really sucks big time with this 11Mb ODS test file - it
takes 14 minutes to load the file.

In contrast, the same ODS file is displayed in MS Excel 16.11.1 (180319) in
approximately 1.5 minutes, a nearly 10 fold difference !



Steps to Reproduce:
1. Open attached ODS file in LibreOffice
2. Count the time it takes to display the spreadsheet
3. Open the same ODS file in Excel 16.11 
4. Count the time it takes to display the spreadsheet.
5. Compare the times taken.

Actual Results:  
LibreOffice Calc takes way too long to open this file.

Expected Results:
LibreOffice Calc should be able to open this file within a reasonable time
frame and certainly at least as fast as Excel.


Reproducible: Always


User Profile Reset: Yes
