RE: I/O and db_file_multiblock_read_count

That's not particularly interesting. Linux has maximum
atomic I/O read  smaller then 1MB (I believe it's 256KB?) so
using 1MB blocks will 

Inevitably break one I/O request into many.

Interesting that the 64K blocksize significantly outperforms
the 1M blocksize.
