Bug ID: 158774
Summary: Serious slowdown in recent Libreoffice calc release
Product: LibreOffice
Version: 7.6.4.1 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]

Description:
On a Calc file containing some large number of random formulas, recalculation
of formulas and general navigation is MUCh slower on LO 7.6.4 than on LO 3.3
Steps to Reproduce:
1.Open the attached file in LO 7.6.4
2.Apply a recomputing (for example with ctrl+shift+F9). On my HP i7 machine,
the recomputing takes 14.80 seconds approximately
3.Now Open the same file in LO 3.3
4. the same operation takes about half the time: 7 seconds approximately
5. also, scrolling of the spreadsheet is normally fast in 3.3, while if you
navigate the cells in 7.6.4 things move way way slower, it is almost unusable
Actual Results:
LO 7.6.4 turns out to be much slower than LO 3.3 on the same file
Expected Results:
Running times should be at least the same, if not better
Reproducible: Always
User Profile Reset: No
