Description Tom Kijas 2016-08-29 14:50:53 UTC

plasmashell freezes OS and takes few mins when searching apps using Kickoff/Dashboard/krunner. 

Every second search of the same app then is fast
After about 10 attempts of searching some apps, it fixes and every search then before next restart is fast as it should be.

Reboot of the computer reinitiate this issue again.

Reproducible: Always

Steps to Reproduce:
1. Reboot computer, login, try to search the app using Kickoff/Krunner/Dashboard
2. Wait few minutes, then it found it
3. Every 2nd search of the same app then is fast
After about 10 attempts of searching some apps, it fixes and every search then before next restart is fast as it should be.


Actual Results:  
The searching of apps after reboot is painfully slow

Expected Results:  
To search fast (as it does after some attempts).

Ubuntu 16.04.1 LTS, 64bit
KDE5.6.5
Nvidia drivers

plasmashell takes about 2MB of IO reading in ksysguard when searching is being done

Oh, and I forgot, I use RAID and I thing it is somehow connected, but do not know how to found whether my opinion is true.

That sounds more like some application is hogging CPU.

Is this issue still reproducible for you with more up-to-date versions of Plasma?
If so, could you check if there's any application behaving weirdly (high CPU or RAM) on your system?
