Description Buovjaga 2022-05-17 14:08:49 UTC

Created attachment 180163 [details]
Perf flamegraph

Download attachment 103519 [details] and attachment 103520 [details] and open the .odm. It is quite slow to work with.

Documents originate from bug 81792 and there is a crash bug, bug 124300.

Perf trace is taken from opening and letting it settle for a while.

With
Version: 7.4.0.0.alpha1+ (x64) / LibreOffice Community
Build ID: 817b8fe7001a83cb74910eb09b7c14a3b95b8a39
CPU threads: 4; OS: Windows 10.0 Build 19044; UI render: Skia/Raster; VCL: win

About 15 seconds with a high usage.

Maybe in relation with 22 tables and 588 footnotes in the document.

Buovjaga, does the problem still exist in actual master or in LO 7.6? What ist the result you expect?
=> NEEDINFO

Comment 3 Buovjaga 2023-09-02 11:00:54 UTC

I think it was the comments. I don't repro anymore with 7.6. Checked with 7.4 bibisect repo that it was slow when scrolling past comments.
