Yes, you can replace your Netgear ProSafe for a gigabit switch and get an increase in throughput (and you'd need to hardwire the systems too, 802.11g is probably giving you about 50% of the theoretical 54Mbps). However, you may not be getting full gigabit speeds even after upgrading. Gigabit exposes other bottlenecks in a system. How fast can you get data off your disk? How fast can you push that data across the PCI bus?
This is a link describing the <50% for 802.11g
I've used iperf in the past to test network throughput.
