https://bugs.documentfoundation.org/show_bug.cgi?id=147283 Caolán McNamara changed: What|Removed |Added Status|NEW |ASSIGNED Assignee|libreoffice-b...@lists.free |caol...@redhat.com |desktop.org | --- Comment #22 from Caolán McNamara --- I'll take this because I've some work done looking into it. Fundamentally the font used for the bullet doesn't appear to have the selected symbol in it and this is a glyph fallback case so it might not be a mainstream problem. What font is used for the glyph fallback may differ from system to system depending on what's available for use so we might be seeing different results. Anyway, the commits I'll push bring it from from 8 seconds to 3 seconds to convert this on the command line for my setup. https://gerrit.libreoffice.org/c/core/+/130892 https://gerrit.libreoffice.org/c/core/+/130877 -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=147283 --- Comment #20 from Caolán McNamara --- I think we can ignore comment #17 as twaddle. Looking at it a little more, the glyph fallback is from "Noto Sans Symbols" for codepoint 0x25aa. That font doesn't have this bullet, fontconfig suggests that we could replace it with "Noto Color Emoji" *but* additionally suggests we apply an extra matrix to skew it. Back in bug #32665 we disabled the cache for "emboldened" and this sort of "fake italic" glyph fallback suggestions. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=147283 --- Comment #19 from Timur --- I amend the title with "on 1sr run" because only 1st run is slow, 2nd run of the same command is fast. Applies both to 7.3-oldest and 7.4-master, both for default attachment 178523 and custom attachment 178524. So title seems wrong from the beginning (did you run custom first and then default without clearing from the memory or reboot?). (Seems that 1st run was becoming more slow with newer LO, from 8 to 34 secs for me. But I didn't check what's exported). -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=147283 --- Comment #17 from Caolán McNamara --- It is possible this is the same type of problem as bug 137571 and relating also to bug 123470 If the problem exists in trunk right now it is possible that deploying the same fix of an ActionGuard in the right place (as used for bug 137571) could be useful. -- You are receiving this mail because: You are the assignee for the bug.

But I'm just speculating :)... No pb! Retrieving a Flamegraph is quite easy and requires not much time so don't hesitate to ask if it can help Of course, it's useless to systematically retrieve a Flamegraph for all perf bugs if nobody gives it a look in the following days/weeks since the code may have changed more or less in the meantime. But knowing Caolán's reactivity, I suppose there'll be no pb for this one! :-) -- You are receiving this mail because: You are the assignee for the bug.

The flamegraph shows clearly why this is Linux-specific. It spends a huge amount of time in fontconfig called from psp::PrintFontManager::Substitute; so it looks like missing font issue, caching issue, and maybe fontconfig performance issue at the same time.

Besides, when working on a performance issue, it's easier to see the improvements when the differences are longer than just a few seconds.
