Hi Tantal,
Be happy it's only 10 seconds in your case

On my system (0.5b on RPi 3B+ with DigiOne Signature) it takes a whopping 30 seconds to refresh the (web)interface.
It seems to be related to the last.fm service, but this problem is lasting for several days now.
I use my RuneAudio setup every day, and this issue is a huge pain in the behind.
I started testing both Volumio and Moode, these systems don't seem to have this problem.
I really like RuneAudio, but I also like to have a properly functioning system.
Choices, choices....
