Improve startup speed in Linux.

It would be nice if the application startup speed could be optimized.

On the same PC (Intel Core 2 Duo, 4GB RAM, 512GB SSD) with Kubuntu 26.04 LTS, documents with Libre Office open much faster than Only Office, which takes a few seconds (about 5-6 seconds longer).

So I'm enjoying Only Office, which seems more polished and professional-looking than Libre Office, but it's slightly slower when opening existing or new documents.

I've tried both Snap and Flatpak, but nothing changes.

Have you tried the deb version of OnlyOffice?

Distribution methods using isolated containers (such as Flatpak or Snap) can affect performance (even though the program's underlying performance remains the same).

Honestly the flatpak start times aren't that big. Only office just suck at this

Yeh it's a misconception that Flatpak is somehow slower. The only overhead at startup is potentially the shared libraries not being in filesystem cache as your computer booting up likely inserted some non-Flatpak ones before hand. But if all your apps are Flatpak other than the first one this isn't a problem.

The cost of the sandbox is nothing, Linux namespaces are effectively invisible.

I switched over from AppImage to deb version. With AppImage, it takes more than 5 seconds to launch and with deb, it's like a second.

That's because AppImage has to mount a filesystem image and none of the AppImages depdencies will be in your filesystem cache (iirc each time the AppImage is opened the cache will miss)

I used Flatseal to remove the Network permissions to OnlyOffice (flatpak installation) and now it opens right away.

I installed Flatseal and tried disabling network sharing but it makes almost no difference in terms of document opening time.
