Logging into a MC server is much slower than it was before.

Before, such as 1.2.5, the log in to servers would go to the "Connecting" and then "Logging In." Now, 1.3.2 and on, at least on my computer, it lags for a while showing the server list and then quickly flashs the "logging in" screen and then logs me in. This is really frustrating because it takes forever to log into servers. Before it took like 5 seconds.
