7206 VXR NPE-G1 throughput

We're still on the 12.4 train. I do use an ACL with less than 100 
entries which handle BCP38 and block a few bad actors and private IPs on 
the Internet. I will be moving the BCP38 ACL closer to the hosts before 
the upgrade so the ACL will be a bit shorter in the future. We won't be 
doing any QOS or IPv6 on it but it does take a full BGP table. I just 
need it to last another year or two out of it if possible. I believe 
this platform goes End of Support in  Spring 2016.
