I am trying to run AprilTag for ROS using bluefox2. The usb camera has a default fps of 30. However, when I am trying to detect Apriltag, I am getting an detection rate of 7.067.. or 8.34.... It never exceeds 9.

In the link , they have tabled the fps they get. As per them, it should be atleast 14 on laptop using 13 4th gen. Mine is i3 7th gen but I dont get it beyond 8 or9.

What can possibly be the reason?
