FG-60 & FG-100 Scalability?

[#1]

I have been reading this complete forum (which is awesome by the way) and am a bit concerned about the actual performance of the Fortigate units. We have procured 2 units: FG-60 For our Internet connection: (1 cable / 1 dsl modem) -With 30 or so connections using internet -NIDS, AV, NAT enabled FG-100 to put in front of a Cisco Router for another wan segment (transparent mode) -30-40 units -100 Mbps LAN (Rarely hitting 100Mbps) -AV Only Can these boxes actually handle this spcific type of load? Based on the info in these forums: -Seems actual overall capability of Product Line is LESS than Fortinet claims -Adding in TOO much into a unit really pushes it over the edge (VPN, Hosting, URL, E-mail Filtering PLUS NIDS & AV) -Issues with the FortiOS itself We' ve got 30 days to evaluate which is why if they can in fact NOT handle we' re not going to keep... Thank you in advance!
