My collection contains 767 albums (10014 songs).
When browsing by album the first load is very slow causing MySQL to use 100% CPU and finally causing a timeout in the browser.
Subsequent browses are quicker but scrolling to the bottom to display the next n albums results in the same behavior but no timeout since it's quicker.
