Version: 1.4.5 (using KDE KDE 3.5.6) Installed from: Ubuntu Packages OS: Linux Trying to build my > 200 GB collection to mysql is very quick for the first 20%, but get slower and slower towards the end. Disk activity is less as well. It seems that there is some O(n2) complexity in the code. My guess is that amarok is looking up artist/titles/album info in memory to see if it indexed some before. Which in my case is not very optimal.
Amarok 1.4.x is in bugfix-only mode as development is focused on Amarok 2. Unfortunately your bug will very likely not get fixed, as the risk of regressions is too high and the Amarok developers do not have the resources for it. Thank you for your report though. Please don't hesitate to report new bugs should you have any problems with Amarok 2 once it is released.
Amarok 1.4 is no longer maintained.
