I score badly on this one and expect many others will too. Is this really going to have much of an effect for the average site or just the big image intensive ones

Reducing cookie size is only one solution to the problem of cookie-related latency.

Another is setting the cookie path attribute differently from the ubiquitous “/” means that the cookie will be resent upstream by the browser for each external file requested, including images, javascript and CSS files that have no use for cookies. Setting your static content in a different folder than your code and NOT specifying path=”/” solves this problem.

Yet another method is setting the cookie’s domain attribute: set your static content to a different subdomain than your code and limit your cookie’s domain to the code’s domain.
