Why is my network throughput so different from my provider's bandwidth?

Last week, we had installed a 50 MB Ethernet circuit for internet. The technician tested the circuit by attaching his Ethernet cable to the Cisco ME 3400E Ethernet Access Switch (CPE). The circuit tested at 56 MB down and 46 MB up.

I have connected the CPE to a Netgear JGS524 Gigabit Ethernet Switch. When I connect to the Netgear switch with my laptop and set a static IP, I go to and my speeds are 9 Mbps down and 750 Kbps up.

A SonicWall NSA 240 is also connected to the Netgear switch and when I connect my laptop to the SonicWall and test, my speeds are 1 Mbps down and 1 Mbps up. SonicWall IPS Throughput is stated as 195 Mbps and Gateway Anti-Virus Throughput as 115 Mbps.

I am confused why I cannot approach the rated speed of the Ethernet circuit. Please explain.
