Bug ID: 400364
Summary: Task manager is too slow for managing large numbers of
programs of the same type
Product: plasmashell
Version: 5.13.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Task Manager
Assignee: h...@kde.org
Reporter: marti...@mailfence.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
Task manager is too slow for managing large numbers of programs of the same
type.
STEPS TO REPRODUCE
Use the default Plasma5 panel configuration in which tasks are shown on the
task bar.
Create 50 instances of Konsole and try to switch to the lowest one in the menu
being generated.
OBSERVED RESULT
It takes 2-3 seconds to build the menu that allows one to switch between
Konsole instances (with 5GB RAM free).
EXPECTED RESULT
The menu should be built in less than 100ms or at least a factor of 20-30
compared to the current performance level.
SOFTWARE VERSIONS
KDE Plasma Version: 5.13.4
KDE Frameworks Version: 5.49.0
Qt Version: 5.11.1
ADDITIONAL INFORMATION
https://github.com/NixOS/nixpkgs/issues/49162
RECOMMENDED CHANGE IN PROCESS
Add performance test for this feature to your continuous integration solution
such that this won't be a regression in the future. Specifically, I would like
to see a graph with number of konsole sessions managed vs the time it takes to
build up the menu and I would like to see a linear scaling in the graph.
