Just want to hear other opinion. 5900 appliance comes with SMT enabled: 16 hyperthreaded cores that by default are split to 14 for CoreXL and 1 for SXL. We are planning to use 2x10Gb bond as a trunk to the core therefore I was thinking if it would be wiser to use two CPU cores for SXL (having additional redundancy/capacity in case one gets saturated) and leaving us with 12 hyperthreaded cores for CoreXL. Before you ask - I have no idea about throughput levels - it will be deployed as a new segmentation firewall so we have no idea what to expect. Guestimate so far couple of gig. And blade wise we won't go nuts from the start - FW/IPS/AntiBot/IA most likely.
