I am doing the Junos Introduction course and came across this graph. It shows the maximum throughput for each family of devices. Why is SRX family so much lower compared to EX? Being a Firewall I would have thought SRX would require a large throughput.
Generally speaking, firewalls have to look much deeper into a packet than a switch or router needs to look and that takes extra processing power and time. Firewalls also have to do data analysis and lookups, too. So as a general rule firewalls tend to have lower throughput than a comparable router or switch.
