Hi,
Just i need your confirmation. If the throughput of my firewall increased and the policies are enabled.... the CPU should increased or decreased?
also if i disable the policies what will happen to the cpu?
also how can i estimate the packet drops on the interface? by pushing more traffic and enable or disable policies?

cheers.

1. If the firewall is processing more traffic, then CPU will increase.
2. Regarding disabling policies - it depends on the firewall.  For some firewalls, disabling policies turns the firewall off and CPU goes down.  For some, there will be no effect.
3.  Packet drops are determined entirely by the type of traffic.  I've seen customers with huge amounts of packet drops due to address scanning and/or misconfigured devices on the subnet.  I've seen customers similar connections that have hardly any packet drops.
