No. While I was at my former employer, we took our edge ACL into the Juniper POC lab, and verified that an M40 stuffed full of OC48 linecards could sustain just over 85% of line rate with our edge ACL applied before sustaining packet loss; the POC lab engineers double checked and verified that there was nothing wrong with the test, that was simply the most the IPII processors could handle with that particularly hairy ACL.
Was that in the limits of the FPC ? It seems it does, just checking out. Was this a test with smallest possible packets ? Do you remember aggregate pps being routed ? It seems you could hit some of the real IP2 pps limits with ACLs, which is definitively not 40 Mpps. In one test I saw it hitted top at 12.5 Mpps, but it may be due to hitting FPC limits. Other people tests showed something in the 20-25 Mpps range. Rubens
