Bug ID: 125236
Summary: looks like the "Bug 54638 - Too slow to load/save file
with lots of cells with multi-line contents" is back
Product: LibreOffice
Version: 5.2.7.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: dv.underwo...@gmail.com
Description:
Hi,
since I don't work now with such calc files regularly as I did years ago, only
recently I noticed a possible regression of the Bug 54638.
You can simply test the same sample attachment from that (Bug 54638).
Even if I reset the LO profile (remove the whole profile
"~/.config/libreoffice/4/") and start from scratch, create the same content
into a new ODF v1.2 extended (default) save file (which for an instance will
have about 451KiB when saved), makes no difference, still takes very long.
Load:
Opening it on the more powerful (PC 1) takes about 16 seconds.
Opening it on the less powerful (PC 2) takes about 9 seconds.
Save:
Saving it on the more powerful (PC 1) takes about 5-6 minutes!
Saving it on the less powerful (PC 2) takes about 8-9 minutes!
While the duration of load in seconds is still tolerable, the SAVE in minutes
isn't.
In both SAVE cases, only one CPU core is 100% utilized during all that time.
Thank you for checking it.
Steps to Reproduce:
Load or save the sample attachment from (Bug 54638).
Actual Results:
Takes minutes to save the sample.
Expected Results:
faster saving/export behaviour
Reproducible: Always
User Profile Reset: Yes
OpenGL enabled: Yes
