I need *your* benchmarking help!

 i tried to diff the sql dumps but diff kinda freaks out so its no real help 
here because of the 0 vs NULL Values in master/jeffs versions plus the artist-
id also changes between the dumps  (case (in)sensitive stuff?) 

jeffs:
	tracks 20,897 MyISAM utf8_bin 5,1 MiB
	urls 20,896 MyISAM utf8_bin 10,2 MiB
	collection showing 20891 tracks

master:
	tracks + urls: 20,896 entries, utf8_unicode_ci
	collection showing 20896 tracks
