I opened a ticket with Spotify support a couple of weeks back to troubleshoot the fact that the SpotifyHelper.exe processes seemed to be using constant CPU of around 8% to 10% no matter what I was doing in Spotify, even if I wasn't playing music.
I provided what I thought were pretty good details to replicate the issue and then my ticket got closed without any resolution. Awesome, thanks for that.
As such, I thought I'd come here to try get some visibility for this .
Open spotify on Windows, open a playlist and play songs. The SpotifyHelper.exe processes all sit stable at 0% CPU. There's the odd spike but definitely nothing constant.
Click an artist name in the playlist to take you to the artist page or search for an artist and open the artist page (i.e. Pearl Jam). As soon as the artist page is open, one of the SpotifyHelpers will start consuming CPU at a constant rate. On my quad core this is between 3 and 5%, on my dual core it's between 8 and 10%.
What's this process doing? It's not playback - if you end the process playback continues fine, the artist page will refresh and the process goes back to it's constant rate. If I go back to the playlist, it usually still sits at the constant rate but I've noticed sometimes it will go back to 0.
Pause playback at it will keep using CPU.
Granted, we are not talking about a lot of usage here on my quad core. But on my dual core 10% is not insignificant, especially when I can have Spotify open all day.
To me it looks like Spotify is constantly doing something to render the Artist page - Please optimize this!
