[Bug 1825513] Re: High CPU usage when large document open
Hmmm, after some digging into this issue with Tim, we may have uncovered the culprit. It looks like the 'LanguageTool' LibreOffice extension is causing the high CPU load, not LibreOffice itself. When installed, opening a large document will send LibreOffice's CPU usage skyrocketing. After a few minutes (depending on the size of the document), the usage does eventually drop back down below 5% again. When uninstalled, opening a large document inhibits a short spike in CPU usage, but quickly drops off.

Further testing has revealed the issue to lie with a LibreOffice grammar extension called LanguageTool. This is a known issue in LanguageTool and removing the extension resolved the issue.

Tim, would you mind filing an upstream bug report for this at https://bugs.documentfoundation.org/enter_bug.cgi?product=LibreOffice&format=guided and sharing the link to that bug here?

Hi Marcus, thanks for taking the time to look into this. You're right, it doesn't seem like the lorem file I generated consistently generates the bug, at least on Ubuntu 19.04 (the initial bug was reported under 18.10). I'm away from home and don't have access to 18.10 to test right now. I do have another file that consistently spikes CPU that I can share for testing purposes, though I'd rather not post on a public bug tracker. Is there any way I can forward a copy to you? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825513 Title: High CPU usage when large document open To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1825513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Tim, I'm battling to reproduce this issue on Build ID: 1:6.2.2-0ubuntu2. I'm using the attached 300 page lorem ipsum document. Could you please try this document yourself and let me know if the same problem occurs. If not, could you provide another that definitely causes the issue.
