Hi guys, I'm laying Ethernet cable in my house, and instead of paying a costly contractor to do it, I decided to go down the DIY road.
I'm using CAT6 cable (with Baynet connectors) and have successfully terminated and tested the wire. However, I can't seem to get Gigabit speeds when connecting two computers (even directly). The file transfer starts at ~200MB/sec and then drops down to around 20MB/sec and settles there (see screenshot for details).
To test, I bought a pre-made CAT6 and a CAT5 patch cord. All three cables give me around the same results. So I'm wondering: where/when will I see the benefit of CAT6? And how do I get Gigabit speeds? Any help is appreciated!
There is a big difference between negotiated speed, and actual sustained transfer rates.
Negotiated speeds is just the peak speed hardware can agree to run at between each other. And that is what shows up in your network connection status.
But actual transfer rates...that depends on a HUGE amount of different factors.
*Hard drive performance of host source, and health of that hard drive
*Operating system of source
*Network card of source
*Security software of source, such as antivirus real time protection
*Hard drive performance of destination source, and health of that hard drive
*Operating system of destination
*Network card of destination
*Security software of destination
*Whatever network equipment is in between the two
*Motherboard/chipset of both sides
*Health and optimization of both sides

I would look hard at the network card properties on both computers, the parameters there are often the culprit (you may want to enable jumbo frames, turn off TCP Offloads, look at all other settings).. This may help a bit: http://www.speedguide.net/articles/netw ... ation-3449
If both Network cards are configured right, you should be getting much higher speeds, I know at my place with a gigabit Asus router, and over a Netgear gs108 switch, I get over 60MBytes/s just copying large files between Windows 7 and a Linux NAS box I built.
As YeOld mentioned, many factors affect transfer rates, I'd definitely check CPU utilization on the machines while transfer is in progress.. Also, keep in mind transferring many small files will always be much slower.
