openSUSE 13.2 (Harlequin) (x86_64)
I need help trying to track down general system sluggishness during boot and general usage.
When openSUSE 13.2 was newly installed, January 2015, it ran pretty quick. I’ve been keeping up with system updates as well, so have the latest packages. What I have noticed is that, perhaps starting five months ago(?), the system starting booting much slower and general GUI interactions are delayed/stalled.
During boot: The system would get to the splash screen and then hang for a while. I would hear the hard drive quietly click at regular intervals and then finally finish loading to the full GUI. What things in dmesg should I look for to see what is hanging things up? Any other analysis tools?
During usage: After the full GUI has come up, when I click on Firefox, there is a long delay, like minutes, before it starts up. I’ve noticed that perhaps Apper is completely monopolizing the internet connection? As soon as Apper finishes and issues a notification for updates, Firefox immediately starts up. Is there something hanging the system that is waiting on internet services to be up? At other times, clicking on an icon on the desktop or trying to use the Start Launcher menu will hang as well. How do I go about tracking down what is causing this?
I’ve tried monitoring what runs by using “top” after full GUI startup. I see these executables:
Thanks for any insights!
