Bug ID: 464467
Summary: Updates page is super slow when it has a lot of
offline updates
Classification: Applications
Product: Discover
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: PackageKit
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
CC: aleix...@kde.org
Target Milestone: ---
STEPS TO REPRODUCE
1. Use offline updates
2. Open Discover
3. Click on "Updates" when it has 517 items to update
4. Click on the list item for the offline update
5. Click the "More information button
OBSERVED RESULT
After step 3, the Updates page opens but it's slow and laggy.
After step 5, Discover hangs for about 30 seconds.
EXPECTED RESULT
No lags, no hangs, good performance.
ADDITIONAL INFORMATION
No such issues seen with interactive updates.
After step 5, the following is printed to the console:

[and about a million more of these; too many for Bugzilla to handle without me
chopping off the output]
