Polysoup is slower.

think about 10,000 polies that define a mesh.
encapsulate that with a geometric shape, such as a sphere.

perform collision testing on the sphere.
then perform collision testing on the 10,000 polygons.

clearly for fine detail you will need to use the polies, but if you can use the spheres you would stick with them only.

you use the spheres as your first line of contact, from there you drill down till you are happy.

staying away from polysoup as much as possible is the way to go, and using convex hulls when possible is cheaper.
some cases polysoup is the only way to get decent collision response.

Thanks. Do you use 3ds max? If so, do you still use the old exporter and link manually
