High CPU Usage on Debian 8 Jessie #1985

Closed cares closed 3 years ago

Hi Guys,

great work you have done with that player :) and i love it +100

and i blogged about it as beeing cool http://dwaves.de/index.php/2015/03/19/cool-software-for-linux-jajuk-media-player-and-organizer/

problem: on my quadcore i5 (!) system (debian 8 jessie) jajuk is causing 75% cpu usage… which might be in the straight after adding a lot of music… and might continue for several days? until jajuk completely indexed it’s database?

but 75% is a lot.

i wonder what to do.

best regards :) you can fix that :)

system is Linux DebianGiada 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux

Thanks for the feedback. Apart from indexing and thumbnails creation, Jajuk cpu usage should be near 0% on modern hardware and your collection is not huge.

Maybe your thumbnails are still building ? we you go to "Catalog view", do you have messages like 'building thumb for album XXX" ?

Please also send me privately your ~/.jajuk/jajuk.log file at http://florat.net/contact

No update on this one for a long time, please report some more details if this is still a problem, e.g. some Java CPU profiling using VisualVM or Java FlightRecorder.

If you don't have that, then at least the Stracktrace of all threads of the Jajuk-process via "jstack " could give some hint. Also newer versions may have fixed this as well.
