Description Zakhar 2018-02-28 00:39:31 UTC 
It should be mentioned windows explorer copy and move operations display a very nice dialog depicting transfer speed. I am suggesting dolphin have similar graph like display for speed of transfer. Would make dolphin more complete and feature full along with improve usability.
Comment 1 Kai Uwe Broulik 2018-03-02 07:56:16 UTC 
The problem is in KIO which manages such jobs. Copy job creates a subjob for every file it copies, however, they only report speed after 1 seconds at which point the job has already finished and the next one started. This is why you can see transfer rate for large files but not when copying many small ones.
Comment 2 Kai Uwe Broulik 2018-03-02 07:57:20 UTC 
As for the graph, that has to be done in plasmashell's notification center (I'm its maintainer and am actually a huge fan of this modern Windows copy dialog) but we first need to figure out how to actually get that data to the application in the first place.

+1, me too. It's really nice.

KIO file_unix::copy reports progress 10 times a second or every 512KB, they could some issues elsewhere.

core/copyjob: report speed when copying multiple files

The speed measurement is done in WorkerInterface::calcSpeed currently.
Except it can only measurement for a single file operation.

Add a speed measurement to CopyJob so copying speed is properly reported
even when copying multiple files, each taking less than a second to
copy.

The speed is smoothed accross the last 8 seconds.
