> When you create an SSL connection in Europe to a west coast server there are a number of round trips. If those can be avoided you can cut the latency of the transaction. That is a good thing too. Note that this will at most cut the connection setup time by half, as your premaster secret (RSA) or handshake data (ephemeral DH) still has to cross the Atlantic and get back to you (and the TLS handshake has 2 roundtrips). Furthermore, because of > Generally the key you would give them is for, and limited to, the resources that they cache/reverse proxy, all dynamic data still is supposed to come from your server. So the browser will have to wait for that, while everything from the European mirror is cached anyway.
