One more hint, possibly helping to narrow down the cause: I have these lines at the end of my fstab:
LABEL=Taranis /media/bernd/Taranis vfat rw,nosuid,nodev,noauto,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,sync,errors=remount-ro 0 0 UUID=E098-2BE4 /media/bernd/sdcard vfat rw,nosuid,nodev,noauto,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,sync,errors=remount-ro 0 0 UUID=64f281c4-5799-4608-88e2-cea581f515d8 /mnt/backup btrfs noauto,users,compress-force=zstd:3,noatime,exec 0 0 They are all marked noauto and none of them is currently connected. If I remove or comment all these 3 lines then the slowness disappears! If I then uncomment only one of them, for example only the last line (this is an USB drive) and save fstab the slowness immediately returns. If I then connect this drive (without mounting it!) then dolphin is fast again. So the symptom can be described as such: * If there is a noauto entry in fstab and the device is not currently connected then dolphin exhibits a delay of 500ms on every click during folder navigation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946061 Title: dolphin: 500ms delay when closing tab, folder browsing slowed to a crawl since upgrade to 21.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/1946061/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
