There is zero I/O during the run (the DB files are already cached in RAM), which is is one of the main reasons I prefer this benchmark to rebuild library / scan for files. The I/O of reading the files introduces a lot of overhead unrelated to the DB performance, and increases variability (e.g. due to file system caching). I've posted the (quite promising) results in the ' other thread ' (https://forums.slimdevices.com/showthread.php?109460).
