if it wasn't picasa, it would have been something else. I mean if I kill picasa ( later on it was done indexing new pics anyway ), it would have been for virtualbox to thrash the io. So, nope, getting rid of picasa doesn't help either. In general the systems responsiveness or sluggishness is dominated by those io operations going on - the DD & CP & probably VBOX issuing whole bunch of its load for IO. Another way I see these delays, is when I leave system overnight, with ktorrent & juk(stopped) in the background. It takes some time for WM(kwin) to work out ALT+TAB the very next morning. But this might be because the WM(kwin & its code) has been swapped out, because of long period of not using it. But, in general, I have troubles with responsiveness, when I try to restore my virtualbox image from saved state. If there is a DD doing its stuff while virtualbox is restoring its image, I see those nasty delays - the kwin, mouse pointer, etc... thanks Aidar PS : the good thing is, and I am getting used to it, I don't loose data, I mean the system doesn't hang, just freezes for a while :) On Thu, Oct 28, 2010 at 5:16 PM, Pekka Enberg <penberg@xxxxxxxxxx> wrote: > * Pekka Enberg <penberg@xxxxxxxxxx> wrote: >>> On Thu, Oct 28, 2010 at 9:09 AM, Aidar Kultayev <the.aidar@xxxxxxxxx> wrote: >>> > Find attached screenshot ( latencytop_n_powertop.png ) which depicts >>> > artifacts where the window manager froze at the time I was trying to >>> > see a tab in Konsole where the powertop was running. >>> >>> You seem to have forgotten to include the attachment. > > On Thu, Oct 28, 2010 at 12:00 PM, Ingo Molnar <mingo@xxxxxxx> wrote: >> I got it - it appears it was too large for lkml's ~500K mail size limit. >> >> Aidar, mind sending a smaller image? > > Looks mostly VFS to me.
