Do both machines have similar hardware? If the Linux machine has a proper NIC (intel, for example) while the Windows
machinehas a poor NIC (Realtek!), then of course you would get differences in performance. 

I'm not saying Microsofts network stack is particularly good, mind you, just that it isn't necessarily the main cause.
Oneof the problems Windows is facing is that, while supporting a lot of hardware is a good thing in general, it also
supportsall the crap hardware, crap drivers and crap ACPI implementations.
