Here are a couple from another thread:

From looking at them as well as a couple that I run, I'm seeing a spread of anywhere from 0.45 to 1.74 seconds of wait time between my browser sending the initial GET request to the server and transmission of the content. During that time the Sonic.net servers are executing the Wordpress code, talking to the database server, and so forth to produce the HTML. Once my browser has the HTML it goes off and requests the various other elements of the page (css, javascript, images, what-have-you). For those subsequent requests, I'm seeing response lag in the 30-50ms range.
By contrast, the main Sonic.net site has a ~220ms lag for me at the moment, Google has a 307ms lag, and NBCOlympics.com has a 152ms lag.
An off-Sonic.net Wordpress site run by a friend and former coworker of mine clocked in at 837ms, and had so much additional content that it took fully eight seconds to finish retrieving everything. So of that eight seconds, one was Wordpress, and seven were his Instagram badges, Twitter API calls, and one really big screenshot of a Playstation game.
