Overhead of sampling a covergroup every clock cycle

In reply to dave_59:

I just want to find out the simulation time/memory overhead when i sample at every clock edge instead of calling covergroup.sample at the right instant. You can assume the complexity to compute that instant and the complexity of bin expression is negligible.
c. That’s something I am not doing. Could you please tell me how to do that ?
d. Probably around 1000 clock cycle.
