Does block size effect Miner's Hashing speed? From my last question:
Bitcoin Block Size - What are the rules?

I learned that the block size can vary from a few kB up to a MB. This leads to my next question:

Does the block size effect a miner's hashing speed? (i.e does a very large block decrease hashing speed?)
If so, what are the details of that relationship?
Only block header gets hashed, and it has fixed size, so the total block size doesn't matter.

From Wiki:Block hashing algorithm


  The body of the block contains the transactions. These are hashed only
  indirectly through the Merkle root. Because transactions aren't hashed
  directly, hashing a block with 1 transaction takes exactly the same
  amount of effort as hashing a block with 10,000 transactions.
