tl;dr ===== * CPU usage at runtime decreased by 150 to 275 percent on overlap-check-heavy tasks
Oops, that should read "15000 to 27500 percent" or "150 to 275 times". Max
* No additional performance problems at loading time (in theory has the same runtime complexity as a single overlap check right now; in practice I could not find any problems) * Decent RAM usage (40 kB for a 1 TB image with 64 kB clusters; 40 MB for a 1 PB image etc. pp.)
