Gigabit Network Speeds (Full Duplex)

Recommended Posts

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,

EBrown

It should be full duplex, sending and receiving at the same time. I have not seen such speeds in practice myself until today. I use free FileZilla Server for file sharing across the LAN. FZ was miles ahead of Windows file sharing before they added SMB2. It is very fast on any computer, and can connect obsolete Windows to modern easily.

There is one gigabit switch between the machines and the other machine has a Realtek NIC.

Simultaneous up/down.

Single transfer.

I'm always defending the old and proven. Not meaning to offend anybody, just sharing my experience.

Well with a switch between them, it got up to about 1.1Gbps, which is statistically irrelevant. Without the switch (crossover) it got up to 1.5Gbps.

I think the bottleneck was HDD transfer speed.

And I'm not at all surprised by my results - Full-Duplex should always be capable of this.

Thanks,

Woah, 1.5GB per second? that's crazy. How did you do it?
