when i added CCCS, the simulation performance was extremely slow. is this due to settings issues, computer performance problems, or other reasons?
v2.009, windows10, RAM 128G, CPU Intel 9980xe, 2080ti and Studio 581.57
The CCCS doesn't speed up a simulation - instead, it makes it possible for cloth to undergo much more rigorous collision resolution.
In your sim, the balls are falling very fast (gravity is high), and when they hit the ground they generate a ton of collisions - basically flattening and collapsing in on themselves. Once the CCCS kicks in, it has a really tough job of resolving those collisions - and the result has a lot of artifacts. Just drop the time step down, so that collisions are resolved in a way that doesn't also involve large velocities. Smaller time step = smaller velocities = it's easier for the CCCS to resolve the collisions. As you drop the timestep you can also reduce Particle Bind Solver steps to help speed things up a bit.
Also your shape mesh is hires spheres, which do not have uniform topology...that adds its own issues. Try the geosphere shape instead.
