For me, DNN 6 is slower than 5.6.3 but somehow smoother. But since my plan is on shared hosting, i really can't be sure about it.
A lot of it seems to have to do with the heavy use of JavaScript in DNN 6. Particularly, the jQuery and AJAX libraries that are heavily relied on.
I don't remember how much JavaScript DNN 5 used, but it was a lot less.
While jQuery and jQuery UI, which are used in DNN 6, provide a lot of cool functionality, it has been shown to increase page load times, processing times, etc, as compared to JavaScript that is specifically tailored to a certain task. This is because the entire library has to be accessed each time a jQuery function is called.
In DNN 6.2, which is still buggy, they added options to minify the CSS and JavaScript and combine them into a single file, which will help this issue, as there will be less requests with a consolidated file, and a smaller file size, since it's minified.
If you use IIS dynamic and static compression, heavy caching, and use the 6.2.x version, after they work out the bugs, I think you'll see minimal performance decrease. They seem to be ironing out the bugs and increasing performance as they iterate on version 6.
