            Bug ID: 131709
           Summary: Copying a large sheet is very slow - II
           Product: LibreOffice
           Version: 6.4.0.0.alpha0+
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
i 'm in doubt if i'll ever understand @xisco, whenever i add to an old bug he
want's a new one, if i open a new one he say's 'duplicate' ... 

i wanted to reactivate #125661, the patch left a performance issue: 

0.) still performance issue in special situation, see point F.) below

00.) file referenced is
http://bugs.documentfoundation.org/attachment.cgi?id=150858, mentioned in
https://bugs.documentfoundation.org/show_bug.cgi?id=125661#c0, 

A.) with ver 6.2.8.2 it took more than 4:30 - hours! - to do 'sheet - move or
copy sheet', not finished after that time, killed the task, 

with ver. below (7.0 about 1 week old) it takes: 

B.) 11,5 seconds to open the file provided by the OP, acceptable, 

C.) +/- 2,83 sec. to copy the existing sheet to another by '+' to add sheet and
then ctrl-a - ctrl-c on the old, ctrl-v on the new sheet, good, 

D.) +/- 2,05 sec. for undo after that with ctrl-z, good, 

E.) similar times for copy and undo with 'move or copy sheet' done after! C.)
and D.), 

but! 

F.) more than 4:25 minutes (265 seconds!) to finish if you execute 'sheet -
move or copy sheet' as the first action after loading the file (and starting
the program?), 

thus there is still an unneccessary performance issue, unneccessary as F.)
isn't 'more work' than C.) 

ver. tested: 

Version: 7.0.0.0.alpha0+ (x64)
Build ID: 61d8d991a27c3bfe70e3b8d3b4ce4d8a41d18d2d
CPU threads: 8; OS: Windows 6.1 Service Pack 1 Build 7601; UI render: default;
VCL: win; 
Locale: de-DE (de_DE); UI-Language: en-US
Calc:

Steps to Reproduce:
see above description

Actual Results:
100 times longer for 'sheet - copy or move sheet' than for ctrl-a - ctrl-c -
ctrl-v (after fresh load of file) 

Expected Results:
similar performance with 'sheet - move or copy sheet' as with copy/paste


Reproducible: Always


User Profile Reset: No



Additional Info:
Version: 7.0.0.0.alpha0+ (x64)
Build ID: 61d8d991a27c3bfe70e3b8d3b4ce4d8a41d18d2d

dis - or enabling openGL makes no difference
