I am mostly interested in performance benefits in terms of CPU and I/O system load. I am considering real-time
computer vision application and it looks like the CPU performance is going to be the bottleneck at Raspberry PI.

I am curious to see some measurements. If the difference is significant, it could be a good selling point for PI camera unit!Moving data over the USB to the CPU takes a fair bit of CPU, with the Pi camera, you don't have that overhead so you have more CPU available.
Not necessarily. For example I have Logitech HD Pro Webcam C920 which is a pretty decent camera.Picture quality is usually better than webcams, depending on the price you pay.

Yes. The V4L2 drivers use the same GPU acceleration as the raspicam demo apps.abshafique wrote:How about the v4l2 drivers used for the camera board? Do they perform with the same speed in the gpu leaving the cpu free? I am also considering real time image processing applications.
