A bad score might be anything > 1. For files smaller than 1 MB in size it would scale the ratio to the equivalent if the file was 1MB in size (e.g. a 16kB file with 4 fragments would have a score of 256, which is clearly bad). Large files can have a score much less than 1, which is good. > > Cheers, Andreas Shouldn't be based on fragments per max extent size for ext4? And I think the max extent size for a 4KB page is 128 MB, right?
