I like the idea of more efficient BufferTag->Page data structure. I'm not sure cache locality is a real problem there, but I believe this idea deserves giving it a shot. I'd happily review your proposal and co-mentor project, if it will be chosen for GSoC. Also, plz check some work of my students in related area [0]. Best regards, Andrey Borodin.
