I think most of the loading time is in the images, gifs and web fonts used (the svg a bit, but not so much). These days I don't see much of value in optimizing the slides for after-the-fact consumption (video is much better for that), and I just put them online so people that have actually seen the talk can go back to some of the code, links and references. And in this way I justify my lazyness for not optimizing the load time a little bit :)
