Yeah, a cache line is 64 bytes. If you care about putting data that's used together adjacent you're assuming that objects a lot larger than 64 bytes are the most common case but I'm not at all sure that's true. I would guess that we're using up our memory with large heap allocated arrays and large numbers of structs that fit within a cache line. But of course, that's something that ought to be actually measured.
