@azeey appears this might also be an issue with mesh shapes in general? If you replace the cone with another ellipsoid it seems to have same slowdown issue, both cone and ellipsoid use meshes for collision instead of closed form solvers, that's my guess for the issue?
I'm fine with removing it or also maybe just removing collisions from ellipsoid and cone in that world if RTF performance is more desirable.

When I visualize the mesh, I see a lot of triangles for both the cone and ellipsoid. In shapes.sdf, the cone generates about 20 contact points and ellipsoid generates 1 until it falls over and then ~11 contact points. Would it be possible to limit the number of contact points when we construct the physics shapes? Maybe @iche033 knows

with #2270, we can now set the max no. of contact points for all collision pairs in SDF. For dartsim, it comes down to the SetWorldCollisionPairMaxContacts function in gz-physics. However, we can not set the max contact point for each individual collision yet.

Looking to add cone directly supported in ODE->DART->Gazebo:
