Description jakubby 2022-04-28 09:52:04 UTC

SUMMARY
Thumbnailing an image causes a really big I/O wait time spike(Kde connect, ftp, smb etc.);, which proves tiresome with KDE Connect or other network connections.

STEPS TO REPRODUCE
1.  Use kde connect with photos+videos being shared over the network, or anything which invokes i/o wait time.

OBSERVED RESULT
Dolphin tries to thumbnail everything, which cripples responsiveness and upload speeds over local networks. 

EXPECTED RESULT
Dolphin by default excludes any kde connect directory and remote file systems(imagine thumbnailing 1-4TB of photos+videos[I don't store that amount of data, but I know others who store in the realms of 10TB+]) thumbnail everything, which cripples responsiveness and upload speeds over local networks.

Oh I see now:

It is kinda related, the thumbnailing should automaticaly end on sshfs of kde connect.
