It offers much higher performance due to a number of factors:
1. Hardware Crypto Accelerator chips (Marvell Nitrox V x1, 2 or 4 depending on model) can perform IPsec Encryption/Decryption in hardware.
2. Dedicated inter-chip links between the crypto acceleration chip and the flow offload engine. This allows traffic to be decrypted and encrypted without adding traffic to the system bus.
3. Higher speed internal switch fabric (3.2 Tbps) allowing the use of much higher speed netmods (4 x 200 Gbps and 2 x 100 Gbps plus FTW (fail-to-wire)).
4. Much higher CPU (32 cores, 64 cores or 2 x 64 cores) and RAM (256 GB, 512 GB or 1 TB) to provide system resources for the much higher throughput (65-145 Gbps with firewall and IPS features active, clusterable and capable of multi-instance)
