It is 1, mega bits , not 1, megabytes. A 10 GB archive could be transferred in only a minute and 20 seconds. This speed is incredible, and if you need a reference point, just recall how long it took the last time you moved a gigabyte of data back before USB keys were as fast as they are today. Copying a 4. Topics Business Computing. See all comments Interesting article, thank you.
Hello Thanks for the article. But I would like to ask how is the transfer speed measured. The bus speed makes a big difference. That may sound higher than the maximum for gigabit ethernet and it is, but the bus is shared across the whole system, so you never really get that speed.
Another aspect to all of this is the cabling. If your cables are old or if they are close to power sources, it could affect performance. Also, the length will make a difference if the cables are very long. I plug my computer and NAS into the same switch and then connect my switch to the wireless router. Most routers are also switches and technically you should get the same speeds as a dedicated switch. However, in my experience, a dedicated switch from Netgear or Cisco always tends to perform better than a wireless router that has built-in ports.
You have to make sure you are using the Ethernet port to get the fastest speed possible. I have also noticed that transferring a ton of small files is slower than transferring fewer larger files. Hopefully this post gives you a better understanding of what affects the network transfer speed on your LAN. We also have to take in consideration of read and write times of the drives too. If the drives are slow, so will the transfer speed.

Thats what I was thinking 7 sustained sounds alot like 10mb linkrate. Joined Nov 4, Messages 10, 1. Backplane bandwidth is important if you want multiple machines to be able to connect and transfer sustained high speeds.

I like it for quick "am-I-in-the-ballpark" measurements without the hassle of setting up client and server machines as other methods require. All you need to do is browse to a network share, select the test file size, select the output units Kbps, Mbps, KBps, MBps and start the test. It did better with a Mbps connection between the two test machines, coming up with 81 Mbps vs.
IxChariot's 93 Mbps. Even with this inaccuracy, it beats the manual method of copy, measure and calculate and it's fine for relative measurements. Although there is a free V1. Nuts About Nets produces a whole line of commercial Wi-Fi diagnostic tools. NetStress beats jperf hands down for getting a throughput vs. When you launch the program, it prompts to select a network interface if your system has more than one. You then get a nag to choose a remote adapter via a system notification and a flashing Remote Server IP menu bar item.
You also set data direction, display units and MTU. NetStress' key weakness is that it isn't up to testing Gigabit connections. Figure 2 shows NetStress measured Mbps vs. When I forced port speed on the switch to Mbps, though, Net Stress correlated just fine. NetStress' other annoyance is that it's a screen hog, automatically expanding to take up your entire screen and not providing any way to resize it.
The other way to measure network performance is to monitor what's going on while you transfer a file or folder or stream audio or video. You'll want to use this method to get a profile of video content you intend to stream wirelessly.
Once you know the bandwidth your content requires, you then know what your network has to deliver.
