A DNS cache works only if that address has been requested recently.
With few users, that will be less likely.

I disagree.
Any one web page is also going to request .css and possibly .js files and these days its so close to a certainty as makes no difference that it is going to request some graphics. Those are likely to be from the same server or at the very least a server in the same domain.

If you google for something all that applies and its likely you will read the next page as well.

Depending on your reading habits you are likely when visiting a site to 'follow on' to subsequent pages. All of the above applies. Perhaps a really smart browser will not request the same .css and .js and perhaps not the header image, the next pages will have unique content.

More and more the web is become graphics intense.

So even with one user three is going to be a need for DNS cache.
As Carlos says, a single page may trigger dozens of requests.

Oh and there's always google analytics.
Unless you are unsociable and include that in your adblock list.
