Azure Kinect Body Tracking outputs data slowly, is there any way to improve?

I used simple_3D_viewer to track body in real-time, and output about 6 parameters (body angle, arm angle and others) per round of "while" loop. Every round of data output took about 150ms, and it is insufficient for accurate observation of fast movement, so I wonder is anyone have output data at a higher rate? What can I do to shorten the interval of data stream? The ideal interval is below 50ms.

If possible, add more screen recordings or any logs\images for your scenario?

2022-03-28T23:54:01.19+00:00 Thanks for reviewing my question. I'll show you some images later, but first let me update my question. I found out that when outputting data (coordination of joints, body angle, etc.) with offline_processor, the speed is pretty much the same as 30fps. However, when outputting data using real-time sensor (simole_3d_viewer), the data output interval is about 150ms, so I'm wondering if the process of real-time capture takes time.
