[c-nsp] how ACLs affect the processing of a Cisco 7200 NPE-G2

[Steve McCrory]

Ali,

Have you enable Turbo ACLs?

This features compiles the ACLs and once enabled the performance impact
of a long list is the same as for 1 statement.

It can be enabled with the global 'access-list compiled' command

Hi All,
My question is how ACLs affect the processing of a Cisco 7200 NPE-G2.

1. Does it matter if I have a long list of ACL statements, or it is as
CPU-consuming as 1 statement?
2. Is CPU processing is on a per-interface basis. For example, if I have
one interface with ACL and another without ACL. Is it going to be the
same
in terms of CPU utilization?
