I got my brain-melting first taste of Gigabit networking today, between my 2011 MacMini and Windows 8 Pro desktop connected via Cat.5e to Linksys WRT320N(sporting dd-WRT).

After making sure that the line speed on both systems showed 1Gbps, I proceeded to copying a 2.4GB MP4 from the Mini to the Win 8 desktop (SMB sharing). Although satisfied with the 30-34 MB/s that Teracopy was showing (that was a proper step-up for me from 10 MB/s), I still was curious about this massive difference in the advertised and real-world speed.

2 hours of Google had me believing that there were other factors that resulted in less speed, SMB being one. So just for the sake of doing it, I iPerf'd both the systems and guess what that showed - around 875mbps on both systems!

I then stumbled upon this little piece of info after which I turned off Teracopy and copied the same file through Windows 8's regular copier. 109 MB/s. Molten brains :)

What exactly is causing this? And can I enable such speeds via Teracopy? I really dig the extra features that Teracopy has, will surely miss them now :D
