While using RTMP if the request is tunneled through HTTP, how different it is from a HTTP request?
What would be the performance implications of tunneling while using RTMP?

The advantage of RTMP streams over the casual HTTP based progressive downloading is far too realistic to ignore
You can serve Flash Video over the Internet using RTMP, a special protocol for real-time server applications ranging from instant messaging to collaborative data sharing to video streaming. Whereas HTTP-delivered Flash Video is referred to as progressive download video, RTMP-delivered Flash Video is called streaming video. However, because the term streaming is so often misused, I prefer the term real-time streaming video.
One of the benefits of RTMP delivery for the viewer is near-instantaneous playback of video, provided the Flash Video file is encoded with a bitrate appropriate to the viewer's connection speed. Real-time streaming video can also be seeked to any point in the content. This feature is particularly advantageous for long-duration content because the viewer doesn't have to wait for the video file to load before jumping ahead, as is the case for HTTP-delivered video.
