When launched it uses ~60% of one cpu core

Looks like it's fixed now. ;-)

i'm not sure why that happens. at startup it does several things: it loads all the views content from the db and sets the artwork it also loads some watcher (QFileSystemWatcher)... how to debug this? how do you check how much % of cpus is using?

[milohr]

i just checked with kde system monitor and it appears to be from 17% to 24% maximum of cpu. so this might be releated to QtMultimedia/QMediaPlayer

With htop. That's just cold launch with no changes whatsoever.

[milohr]

going to run some checks but i strongly believe this is something outside my code, cause when using https://github.com/andreisergiu98/music-player-qt5 as a based in the very beginning of my experiments with qt5, that app was -and still -using the same amount of cpu and that player doesn't do much.

Just used the Arch AUR and I get 85% CPU usage on one core.

tonight i will run some testes to find out why is it using so much cpu.

[milohr]

i fixed it. it now uses around from 2% to 5%, although when on the albums or artists view the cpu usage increases up to 17 % - 20%
I'm not sure why that is right now.
For now i'm closing this issue, if you find any more abnormal behaviors please don't doubt in report again. thank you :) if you would test my recent changes would be great!

[mmetak]

Yes, you're right, when on the albums or artists view the cpu increases.

[milohr]

my first though was that the paintEvent method override i made in the Album class was causing it but i removed it and still the cpu went that high. maybe is the way i'm creating the object for each album or it might be the image size storage as the qpixmap... i'm not sure anyway right now, i will continue to find a solution. can you confirm please that the cpu usage decreased in the other views besides the two already mentioned?

[mmetak]

Yes, I can confirm.

[milohr]

@mmetak just so you know i've updated master with a fix for the album/artists view high cpu usage. if you could pls confirm when you have the time that the fixes worked for you too woudl be great.
