Camera lingo help needed please

What does ADR mean? I'm looking at this camera on Amazon and the second review of this camera concerns me. I want a camera that I'm able to take pictures by a click no hesitations. I'm looking at this camera BTW: Nikon



"I really like how small and light the camera is. It is easy to use and I am happy to have a VR lens. I was also excited to get ADR - but, that's where a huge problem arises: I was stunned and disappointed to discover that enabling the ADR inexplicably slows the speed from 3 frames per second to an excruciating 3 seconds per frame (after the five-frame buffer is full). Of course ADR can be turned off, however that was one the main reasons I bought the camera. "
