KDE: Awfully slow file operations

Soukyuu · 2015-01-27 23:35:47

So I don't know what the deal is, but it's been moving ~118mb (two folders with an iconset each) for 3 minutes now, and is only about 30% done. Both source and destination being an ext4 formatted SSD.
I can see a few kio-file processes running and my CPU is capped at 100% on each core. What in seven hells is dolphin doing? A move operation to the same drive should be near instantaneous.

Extracting the same two archives directly to the destination takes a few seconds at most, as expected. Moving the same files via console is as fast as extracting from the 7z archive.

KDE might be generating thumbnails on each file as they are copied. I would try to disable thumbnails before you copy.

You can also try disabling the baboo indexing program, it's notorious for problems like this.

Another option might be a semi-faulty SSD which would explain the speed drops

It turns out I forgot that folder is mounted on my HDD, not the SSD, so it was an actual copy to destination -> delete source operation.

Preview is off, and I disabled the indexer (it wasn't producing any CPU activity anyway), still same problem.

Dolphin is by far the slowest file manager according to my tests:

Setup:

copy 13k icons ext4 SSD -> ext4 HDD, destination folder deleted between runs. Each file manager tested 3 times

Results:

dolphin: 1:23
thunar: 1:17
nautilus: 0:26
windows exlorer: 0:14
pcmanfm: 0:10
command line: 0:02

Double the numbers for move (I guess that's because it has to delete the files as well). Here's hoping they can figure out how to speed it up with the KDE5 dolphin port...

edit: added windows explorer for comparison. It does quite well, surprisingly.

Don't hold your breath My bug report (originally filed against Dolphin) is almost 4 year old, with (strange to me - there is no reasonable question) status "need info". https://bugs.kde.org/show_bug.cgi?id=282500, and a video to that bug report http://youtu.be/M_MDlPa9jeE

I'm not; most things on the linux side of things run the way of "well, it's working, if you want to change it, be my guest".

Btw, the good ol' windows explorer needs 14 seconds and konqueror 1:33 to do the same operation.
