Speed Up Amarok With Large Music Collections

Amarok is a wonderful application for managing and playing your music collection, but the default settings aren't optimized for speed when it comes to large collections of music. The problems are especially noticeable while trying to use the search box.

The problem is that the default embedded database uses sqlite to store the collection information, which doesn't scale quite as well as a dedicated database such as MySQL… so we'll switch to use that instead.
