Thanks Caixuan submitting the issue. We will investigate.
Run the command on master and 1.4.2. InToTree clip x 3 times.
Question about the issue, from the table M7 average speed is less than M6. I suppose this is what performance drop means.
M6 and M7 have very close speed. The gap is really small. I think you need to run multiple time, take average to mitigate variability.
