Hello,
I don't believe we can put a distinct number or impact the CSPC has on a customer's environment. The CSPC is dependent on SNMP to be able to pick up network devices. Larger devices or even devices with more modules may take longer to collect from. We also have the option to pick up additional information by enabling SSH/Telnet, which may cause collection times to be even longer. Since it depends so much on network size, type of devices and what type of data you're collecting from the devices, the impact will vary from customer to customer.
Thanks!
