We have just upgraded FTD 2110 firewall to firmware version 6.6.1. Since the AC element count is 800k, FMC shows a warning message "the number of access list elements generated for the access control policy exceeds the limit for this platform", suggesting to enable "Object Group Search". I have checked Cisco's documentation but could not get proper information, could anyone of you help me?
1. Is it recommended to enable "object group search"?
2. Does it increase the CPU usage of the firewall? The below document says it doesn't affect CPU usage.
