Performance Question ASA/IPS

I have a ASA 5550, so the max connections p/s is 33K, packets p/s is 600K.  I'm looking to add an IPS at my boundary but don't want too much degradation in application performance.    Looking at the datasheet for  the IPS 4510 and 4360 the max connections and connections per second should provide that minimal degredation requirement.  What worries me is the packets per second (600K) that the ASA can process.

How many pps can the IPS process?  I don't see that anywhere in the datasheets for the IPS

Performance Question ASA/IPS


Maybe this information can help you a little bit but I didn't find any doc that states how many pps can the IPS handle.

I suggest you to involve your Account Manager or Cisco Reseller so they can suggest you the best platform for your network.
