            Bug ID: 125426
           Summary: Very slow loading of 12kB ODT, loads fast when
                    contents is pasted into new ODT
           Product: LibreOffice
           Version: 6.2.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: script at vollbio.de

Description:
Most of my ODTs take 25 secs to load in 6.2.3.2., even very small one-word
docs.

I have found two WORKAROUNDS:
1) Remove /home/myname/.config/libreoffice, Now the ODT loads fast, but as soon
as I close it and re-open it loads very slowly again.
2) If I cp/paste the contents into a fresh ODT, then this loads quickly every
time.

The problem disappears in 6.3.0.0.alpha1.


Steps to Reproduce:
1. Load a previously created ODT (example LoadingSlowly_onewordonly.odt,
attached).
2. One of my 8 CPUs maxes out, soffice hogs the CPU, and it takes 25 seconds to
open.

Actual Results:
ODT takes 25secs to load.

Expected Results:
ODT should load within a second, as it is very small.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:

suggested I submit a follow-up here.
