this really depends on the software. a website using a "slow" interpreted programming language (php, python, ruby etc) in a "heavy" application that runs many tasks in the background on each pageload does not compare to a website that merely returns static information, either directly from the webserver or mostly from cache (no or much less need to waiting for cpu to process, or disks to fetch data vs ram). it is easier to just archive and provide access to existing content than to also run all the "invisible" services around that content.
