Description Julius R. 2024-03-08 17:43:35 UTC 
I have an 7-zip archive with more than 20k files, sized at 8Gib in total. In Windows, the extraction with the 7-zip Gui takes approx. 2 minutes. In Linux, the extraction with ark just hangs forever (I waited 30 minutes).

This bug is related to 454268 and therefore seems to affect all archive types - could be merged.

Bug #454268 is not necessarily related. Haven't checked rar specifically, but 7z is somewhat of a special beast, an external 7z executable is used to get information about the contents of the archive, and it's surely really slow.

It's not really an endless hang, your setup is just likely not fast enough to deal with the matter in a reasonable amount of time. Surprisingly the file listing procedure is unusually CPU intensive as mentioned in Bug #457906 and Bug #422142 already.
