This is a re-opening of the frozen tracks PR
It will be a challenging PR to get fully merged but interested users can try the branch out
Two optimizations were added to frozen_tracks4 today including (a) removing the clone module, which was accidentally quadratic and introduced big slowdowns after around 64000 tracks and (b) a change to the generateHierarchy function for the track selector to make it faster
