Handling server load for the Raspberry Pi Zero launch

PHP can easily handle thousands of requests per second, as long as each request doesn't do much. Fetching from a shared memory cache counts as not doing much. You would need to do before you initialize WordPress though.

Right, the idea would be to put the logic at the top of the main php file for wordpress, something like:

  # oversimplified, but...
  $key=md5(http_build_query($_GET));
  $content=apc_fetch($key,$success);
  if ($success === TRUE) {
      echo $content;
      return ;# never invoke wordpress
  }
  # wordpress here
  # some logic at the bottom to store what wordpress
  #   just rendered into the cache
