foobar2000 problem: high CPU usage, nonresponsiveness and crashes with Reply #25 – 2012-10-21 03:43:04 I reduced the lookup patterns to only folder.*front.*artworks.*thumb.*cover.*album.*%album%*.*%artist% - %album%*.*%filename%*.*and now the performance and stability problem is almost gone (I know previous patterns were somehow overkill but didnot ever think this could lead up to worst case scenario ie. 80000*240 file lookups). Anyway foobar now loads/unloads the whole library significantly faster even with albumart view ON.
