[c-nsp] access-list performance impact - 3845?

[jacob c]

I wanted to chime in on my platform as well? When running an basic or extended ACL do both of these run in HW on the 3845? I am also worried about performance.
   
  Thank you,k

Not really because it's much more complex in a software switching
platform due to what you ACL matches at and how deep in the ACL
it goes. Use latest 12.4 or 12.4T code that has better ACL lookup
algorithms. It's all done in the CEF path so it's pretty good.
