Ryan, It isn't loading any framework that slows things down per se. It loads additional logic that defines what features should be loaded and some pieces have shared framework so it doesn't have to load the same items multiple times.

It's not "bogging things down." It is very efficient. However, if you are only using a couple of features it will use more resources and take longer than comparably efficient plugins accomplishing the same features.

I don't fault Jetpack in any way. It's a great plugin built and maintained by a great team. I use it on a couple sites I maintain because I'm using several of the features built into the plugin. I opted against it on most of the sites I maintain because I would only use one or two features and it doesn't make sense to load that logic when I only need a couple features.
