Personally I get a fair amount of stuttering when I mirror any device (iPad mini retina, iPhone 5s, MBP retina early 2013). Its not alot and some people would not notice/care, but it bugs me. Is yours running as smooth as with AirPlay streaming (e.g. what the youtube app does)?

I have tried looking into my wireless network, with no result. I am just not sure if it is as good as it can be but some people don't care, or I should keep looking.
