1 Maximum throughput with UDP traffic measured under ideal test conditions
2 Multiprotocol = Traffic profile consisting primarily of TCP-based protocols/applications like HTTP, SMTP, FTP, IMAPv4, BitTorrent, and DNS.
3Throughput was measured using ASA CX Software Release 9.1.1 with multi-protocol traffic profile with both Application Visibility Control (AVC) and Web Security Essentials (WSE). Traffic logging was enabled as well.
4 Firewall traffic that does not go through IPS SSP module can have higher throughput.
5 VPN throughput and sessions count depend on the ASA device configuration and VPN traffic patterns. These elements should be taken into consideration as part of your capacity planning.
6 Requires a separate license 
7 Half-width modules
8 A/A = Active/Active; A/S = Active/Standby
