The other answers you've already received are on-point, so I won't reiterate those. But in addition, it can be important to ensure that you don't create a brand new session for each page request, as many crawlers disregard cookies. Also, high-traffic servers typically handle this sort of thing via caching, which can be done many different ways, with different levels of aggressiveness. For example, generating static HTML as Matt mentioned is a pretty aggressive (and potentially very effective) caching mechanism. High volume sites often use third-party CDNs to take care of some of this as well.
