Cars slow down when approaching and toll booth speed up goingaway from it,and that affects their "throughput." Ditto packets traversing firewalls.Not if the acceleration lanes are wide enough: 20 lanes of traffic moving at 10 MPH has the same throughput as 5 lanes of traffic moving at 40 MPH. Similarly, a "full speed" firewall may need to have several NICs on each side. Parallelism solves many throughput problems, but rarely benefits latency (except for reduced queue length).
Eh? Here the analogy breaks. Regardless of the number of lanes, ALL the cars/packets were going 65 mph before they hit the toll booth/firewall. You need a hell of a lot of parallelism to make up for that. dn
