Bug ID: 461394
Summary: Listing items in a folder is unusable slow (with all
previews disabled)
Classification: Applications
Product: dolphin
Version: 21.12.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: view-engine: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: kde-20091...@nathanshearer.ca
CC: kfm-de...@kde.org
Target Milestone: ---
STEPS TO REPRODUCE
1. Set your Dolphin view mode to Compact and disable all Previews in
Settings->Configure Dolphin->General->Previews
2. Put a 1000+ songs in one folder.
3. Open that folder in Dolphin and attempt to navigate to one item.
OBSERVED RESULT
Dolphin will start listing the directory and inspecting every single item
(probably to draw an icon). This radically slows down the simple process of
listing the items in the directory so much that a folder with over 1000 items
is completely unusable. This is significantly worse on even a nfs4 mount over
local gigabit LAN.
EXPECTED RESULT
List the items as quickly as `ls --color=never`. For extra detail like Previews
and icons, do this in the background without disrupting the user. Perhaps
prioritize items that the user has selected, then within view of the window,
then the rest in the folder.

ADDITIONAL INFORMATION

--color=never` and this is how Dolphin should perform. Quickly.
