I remember some threads on LKML about larger page sizes on x86.

Not sure on the current status, but you'll want to look into "page cluster".



There are huge pages, meaning you can configure some subset of the pages in a system to be a lot bigger than default (4MB on x86 boxes). I don't think that helps filesystem block sizes any. Or were you thinking of something else?

Yes, I'm thinking of something else.
