Twisted torii are quite complex prims and usually take the longest time to create a physics proxy (on the order of 5 milliseconds or more) and usually use the most memory. Using integer sizes in your case would reduce the amount of proxies stored in the mesh cache and make better use of it. However, torus prims are procedurally generated and don't rely on sculpt or mesh assets and therefore aren't really affected by the changes being proposed in this thread; at least unless the conversation veers towards optimizing the mesh cache in the sim to reduce or eliminate unused meshes.
