As Sup1A already used TCAM for ACLs, it doesn't matter what is the size of
it provided it fits on TCAM (16K entries).

That would depend on wether this traffic goes to a single IP address (or a
low number of them), or the Internet. If you configure it to use
destination-IP flows (might be default) and traffic goes to a single or a
low number of target IPs, you could get the 15 Mpps maximum. Otherwise your
performance will look more like a Cisco 7200 with NPE-225, i.e, 225 kpps.
