Ah, are you using a build ending with -dbg? Those unfortunately mess with the
performance.

I'm getting the same load time with reload with a non-debug build. Yet, there
is something pathological about the document. Like you say in comment 6, if we
scroll the document past half way, it freezes the whole system for a while.

Bug 99803 is at least solved, the replace completes in 6 seconds for me.

I guess I should open a new report for the scrolling freeze.

I tried using a build of the trunk that I checked out yesterday. Initial load
was fine, but when I used File->Reload it was very slow to open. I see a
million of these warnings in my console:

Perhaps I spoke too soon. When reloading the document after editing, it did
freeze up for a long time.

Modifying the document doesn't seem to trigger any issues.

I just tested it with 5.1.6.2. I didn't have any trouble opening the document,
but multiple times it would freeze my entire windowing system when I tried to
scroll through page 16. I couldn't get other windows to respond, even. My CPU
usage seemed fine though. I think the particular issue described here may be
fixed but it's exposing another issue.

--- Comment #5 from Xisco Faulí  ---
** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present on a currently supported version of
LibreOffice 
(5.4.1 or 5.3.6  https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the version of
LibreOffice and 
your operating system, and any changes you see in the bug behavior

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave 
a short comment that includes your version of LibreOffice and Operating System

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3)

http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to "inherited from OOo";
4b. If the bug was not present in 3.3 - add "regression" to keyword


Feel free to come ask questions or to say hello in our QA chat:
http://webchat.freenode.net/?channels=libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

[Libreoffice-bugs] [Bug 99800] Long compute loops when opening and modifying an odt file

[bugzilla-daemon]

https://bugs.documentfoundation.org/show_bug.cgi?id=99800

--- Comment #4 from Nicolas Mailhot  ---
After further testing on the actual document that served as basis for the
testcase, the loops seem to be linked to the "balance column contents" enabled
in some sections.

Unchecking this option removes (so far, crossing fingers) the pathologic
slowdowns on my test system (5.2.1, win x86_64)

So it's probably a broken balancing algorithm.

--- Comment #1 from Nicolas Mailhot  ---
The document does load (on win32 & underpowered Fedora x86-64 chromebook), it's
just pathologically long. It seems writer has lots of problems computing page
and column breaks in this document. I did gave up on document loading several
times, killing writer and restarting it on the same document usually succeeded
(after a looong time).

The issue seems to be inherited from openoffice.org.
