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@lists.freedesktop.org
Reporter: newbie...@gmx.de
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

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
