This means more data per page, which, apart from less total number of pages, also leads to less splitting, and hence less fragmentation. I'm not sure how the off-page texts/BLOBs are fragmented. Otherwise I have no actual information about this. No doubt Vadim (Percona) can tell us all about it. Regards @Sheeri,
