I have a Cisco ASA 5505 (512 MB Security Plus) that's currently serving a 20/5 Mbps fiber line with no problems.
I'd like to upgrade the service to something faster (75/75 or 100/100) but understand the 5505 has performance limitations. Various accounts I've seen estimate that the 5505 can do 75-100 Mbps real world but I understand my mileage may vary. Plus, there's the simple limitation that the ASA Ethernet ports only support 100 Mbps.
Question: What happens if I upgrade to something faster than the ASA can handle? Will the ASA still do it's job (filtering, routing, etc) but limit / slow down traffic to the max it can handle? Or will the ASA become unstable, drop packets or become lax in performing it's security tasks?
Thanks!
