Recently I got a new notebook with quite a noisy harddisk. :( Because of this, I noticed a pattern of periodical disk access when running Amarok. Approx. 30 secs silence, then 30 secs noise etc.
The 30 secs noise phase happened to be the update of the collection (1739 songs). When the progress bar reaches 100%, it immediately starts a second time beginning at 0%! When it has finished the second turn, the 30 secs silence phase starts. I then monitored amarok with atop. I'm not sure whether I interpret the data the right way. The RDSK rate seems to be related to the songs sampling rate. E.g. when playing a 256kbps song, RDSK says 256K were read in the 10 second update interval, for a 128 kbps song it displays 128K. The read rate is constant over time. Fair enough. The write rate (WRDSK) is 0K in the silent phases, but peeks at more than 30000K (in a period of 10 secs) in the collection update phase! Overall disk usage (DSK busy rate) peeks at approx. 60%. It seems to me that amarok writes several Megs of data when updating (once a minute). Is this possible? So I disabled "Scan folders recursively" and "Watch folders for changes". Read rate is exactly the same as before. Write rate dropped to 0K.
