I've ran several tests like scanning mame with 3.103, 3.103a and a very fresh compile 5x in a row each (to avoid diskcaching effects) and they all take nearly exactly (+/- 1 second) the same time.
Memorywise there is a difference in usage when cmpro had to parse a datfile instead of loading a cache file only but that's known and has nothing to do with a memoryleak or something. Nor it has an impact on scanning speed.

Besides the only changes from 3.103 to 3.103a were xml parser import/export related and the rebuild after download feature. Nothing else changed.
