You guys will love this:
I was farting around with my network just now, and I was testing my Gigabit throughput between my desktop and server, and I have some pretty good evidence of having achieved MORE than 1Gbps on the link. (Not in one direction - mind you.)
The actual throughput (send + receive) was stable between 550Mbps (each) to 750Mbps (each). Essentially, I achieved up to 1.5Gbps total throughput.
As is evident in the images, the speeds exceeded 1Gbps total. (And not just by a tiny bit - either.)
Thanks,
