Description Felipe Peter 2018-12-16 08:10:45 UTC

SUMMARY
Searching for snaps like PyCharm and CLion takes a very long time compared to CLI output.

STEPS TO REPRODUCE
1. Start Discover and search for "clion"

OBSERVED RESULT
The search result for the snap appears after 3:48 minutes. 

EXPECTED RESULT
Comparable search time to using "snap find clion" in konsole.

SOFTWARE/OS VERSIONS
Operating System: KDE neon 5.14
KDE Plasma Version: 5.14.4
Qt Version: 5.11.2
KDE Frameworks Version: 5.53.0
Kernel Version: 4.15.0-42-generic
OS Type: 64-bit

ADDITIONAL INFORMATION
Initially searching for PyCharm and CLion took ages, but after that the search was a lot faster, even for other snaps. While Discover was taking its time to find the snaps I tried the CLI option and found the snaps immediately, so snapcraft was definitely available.

I just rebooted my computer, started Discover and searched for PyCharm. It took 3 minutes to get search results. Again, using the CLI yielded results in <1 second. After finding PyCharm, all subsequent searches for snaps in Discover also returned results within a second.

Let me know if I can somehow help tracking down the problem.

Comment 3 Felipe Peter 2019-02-26 14:05:35 UTC

Still existent in 5.15.1.

CLI search for snap finishes in <1s. Discover takes >1 min.

Is there a way to debug this?
