Server Load bei WordPress 404
Alex King über den Zusammenhang von 404s bei WordPress.
It’s a really elegant system and works very well. However, it also means that 404 requests - http requests that result in a “file not found” message - have a much higher impact on the server than a traditional 404 request does. For every 404, the server instantiates WordPress, does some database work to try to see if it can figure out what to serve, etc.
