Omniverse Jetbot example very slow

I am running the omniverse Jetbox example on a RTX6000 inside of a docker container. In a remote viewer the movements of the robot controlled with w,a,s,d are very slow. They improve slightly when I run it directly on the machine, but it is still very slow.

Do you have any advice on why the physics engine seems to be very slow?

I think RTX 6000 is about 2/3 as fast as RTX 2080 which is the minimum recommended card to run Isaac Sim.

If you turn on the fps in the Viewport, the Eye next to RTX Real-time, what does it say?
