Bug ID: 409599
Summary: Read appstream information in a thread
Product: Discover
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: discover
Assignee: lei...@leinir.dk
Reporter: k...@privat.broulik.de
CC: aleix...@kde.org
Target Milestone: ---
SUMMARY
Discover spends significant amount of time on opening in the appstream backend
reading yaml files. The Flatpak backend does its metadata initialization in a
thread and so should Appstream.
AppStream::Pool::load() accounts for 61% of time spent in discover's main
thread until the main window appears.
STEPS TO REPRODUCE
1. Start Discover
OBSERVED RESULT
Takes forever to show a window, more than 5 seconds
EXPECTED RESULT
Shows a window within few hundred milliseconds
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.16.80
KDE Frameworks Version: 5.60
Qt Version: 5.12.3
