About the running speed of M2Track

[freshwk]

Hi,thank you for your contribution. In your paper, you report the running speed of M2Track is 57 FPS. However, i run your model on a single 3090 GPU, it only takes 92s to test all 6424 frames in the Car category. It achieves 69.8fps. I want to know how do you compute the Speed metric, thank you!

The running speed of the same model may vary across different machines. So reporting the exact FPS may be meaning less if the running machines are different. P2B report that they can run in 40FPS on a single 1080ti machine. Since we do not have such a machine, we report a proportional value in our paper for a fair comparison. Specifically, we run M^2-Track and P2B in the same machine and record the average forward times T_m and T_p. And the reported FPS is calculated by T_p / T_m * 40.
