Bug ID: 168566
Summary: LibreOffice 25.2.5.2: Extremely slow saves in
document with tracked changes
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
I have a document that I am working on, or specifically, two different versions
of the same document. One is my print-formatted working manuscript for a new
upcoming novel; the second is a manuscript-formatted copy of the book after
first edit pass, received back from my editor. So both are fundamentally the
same document, just differently formatted.
The edited copy has comments and tracked changes, was ALSO worked on in
LibreOffice by my editor, but has edits copied from a .DOCX-formatted version
of the document. I'm not precisely sure of the workflow, she was in the middle
of converting fully to a LibreOffice-only workflow, with my help. (Yay!)
In any case, what I am observing is that while it takes only 2-3 seconds to
save my working copy of the document that has never been anything but native
.ODT, a save of the edited copy drives a single CPU core to 100% utilization
for nearly twenty seconds, during which time the entire application (but ONLY
LO, not anything else) becomes completely unresponsive. I have seen similar
very slow saves (and sometimes opens) before, with documents exported to .DOCX
as part of EPUB3 creation workflow using pandoc (a necessary step because of
bugs in pandoc's ODT reader module), even if the document is subsequently
converted back to ODT. So I THINK that the issue is "document is, or has been,
or incorporates changes copied from, DOCX format" rather than the presence of
tracked changes. I don't THINK change tracking alone introduces the save
performance problem.
Is this a known issue?
I am working with LibreOffice 25.2.5.2 built from source on Gentoo Linux and
fully optimized for my specific hardware. Hardware platform is Ryzen 9 5900X
12-core with 64GB RAM and mirrored NVMe SSD storage.
