Even the standard client is optimized so that it doesn't need to hash the entire block header if only the last part of it has changed. That last part includes the nonce but not the extraNonce, so a larger extraNonce wouldn't cost anything for the vast majority of all hashes, namely those where only the normal nonce has been incremented. With today's transaction volumes, the cost of hashing the extraNonce should be less than a millionth of a percent for pools with thousands of members. </div> text/html
