STEPS TO REPRODUCE
I test very simple task Right click in file and choose application to open it.
I tested with xlxs file open by OnlyOffice, LibreCalc; image file open by
Ritrettro, Gwenview; text file by Kate. It can be done in around 5-10s in
Dolphin GUI.  When if I tried by open specific app 1st and drag file to app
window, every file can open instantly

OBSERVED RESULT
It didnt crash or broken. It just work with long delay time. Even I open
application, it can appear in 1s only

EXPECTED RESULT
Ofcouse, I wanna it open instant when im using ssd, the free ram and cpu still
are redundant
