As others have suggested, the switch is not likely to be the bottleneck here -- unless it has (and you're using) any Layer 3 functionality, maybe. Also, that 650Mbps is only with the SSM-40; if you have the SSM-20, it's rated for 500Mbps. How's the CPU load (e.g., `show cpu`) sitting on the ASA? I know things get ugly on the 5520 when the CPU gets up to maybe 60% (which happens pretty easily when someone leaves a capture running) -- my kneejerk reaction is to check that if you're having problems. Clearly this is still on-topic, as the ASA runs Linux under-the-hood. ;-) Jima
