lan speed test lite
  • Operating System: Windows
  • Pricing: Free; the Full version is paid
  • Developer: Totusoft

The Lite version of LAN Speed Test is a standalone portable executable of 122KB and basically an older free version of the shareware program. It’s an easy-to-use tool for measuring the speed on your LAN by copying a file to another computer that is located on the same local network. All you need to do is browse to a folder of another computer on the network where you have write access and click the Start Test button.

You will then be prompted to set the file size of the dummy file to be transferred. The default is 20MB, but that will need to be at least 10 times higher to test faster networks, such as Gigabit. The good thing about this tool is you don’t need to set up master and client connectivity; it just needs write access to a shared folder. You can also print the results at the end of the test.

Download LAN Speed Test (Lite)

Note: There is a newer version that is also portable, but it’s the limited free version of the full shareware tool. However, it gave us inaccurate write test results, so we’d recommend sticking with the Lite version. The installer may also contain adware, so download LAN Speed Test portable if you want to try it.

5. LANBench – measure network performance with multiple simultaneous connections

  • Pricing: Free
  • Developer: iPerf

iPerf is a popular and well-known multi-platform command line benchmarking tool. This means it can be run on Windows, Linux, macOS, iOS, and Android devices. To get iPerf running, download the zip archive and extract it onto two computers, then open a Command Prompt on each machine. On the first computer, run the following command, which sets it up as the server.

iPerf3.exe -s

On the second computer, run the below command replacing the zeroes with the computer’s IP address running as the server.

iPerf3.exe -c 0.0.0.0 (e.g. iperf3.exe -c 192.168.0.2)

A speed test will be performed for 10 seconds, giving the results in Megabits per second. To get the Megabytes per second score, append “-f M” to the end of the command (note the upper case M).

Several other commands can be used in iPerf, although we won’t go into that here. They include changing the default port, using UDP instead of TCP, running for a custom time period, transferring a specific number of blocks/bytes, setting MTU, using only IPv4/IPv6, and much more.

Download iPerf

If you’re not a fan of Command Prompt, an option is to use a frontend GUI. There aren’t many free frontends, but one popular with network admins is JPerf. The drawbacks with JPerf are that you will need Java installed on your system, and it’s also from 2009 with an old version of iPerf. You can’t replace it with the latest iPerf, but version 2.0.9 from 2016 works; the included version 1.7.0 is from 2003.

jperf frontend

Run the jperf.bat batch file to launch JPerf. Usage is pretty much the same as with other tools here; on one computer, set the program as server and press the run button. Use the second computer as the client, enter the server IP address, and press Run IPerf. The advantage here is most of the iPerf commands can be edited from checkboxes and text boxes.

Download JPerf

For more advanced users, we did find another free iPerf GUI called PPerf. It’s actually a PowerShell script that will allow you to switch between either version 2 or 3 of iPerf during testing.

9. NetStress – best for stress-testing network devices

  • Operating System: Windows, Mac, Android, iOS.
  • Pricing: Free
  • Developer: Nuts About Nets

NetStress is a free and simple network benchmarking tool created as an internal tool by Nuts About Nets which was then released to the general public. The biggest problem with NetStress is the horrible user interface, which isn’t very easy to see or navigate and only runs as a fully maximized window.

NetStress also needs to run on both computers that you want to test, but one good thing is it can automatically find the receiver’s IP address. To run a test, click on 0.0.0.0 at the top beside the Remote Receiver IP, select the IP address listed in the window, and click OK. The Start button will then be enabled, and clicking on it will begin measuring the TCP and UDP throughput.

How To Get The Server IP Address

Some of these tools require you to run an instance of the program on two computers, one as a client and one as a server. You will be asked to enter the server’s IP address on the client, so you will need to know its local IP address. Experienced users will know how to do that, but others might not be too sure. Here are some simple ways for less experienced users to get the local IP address of a computer.

Downloading a utility that shows the information in a GUI window is an easy option to get the server IP address. Simple IP Config allows editing the settings of installed network adapters, but all you have to do is download and run the portable tool. Then copy the IP address from the lower right and close the program. You may need to select a different adapter from the drop-down if you have more than one, such as Ethernet or Wifi on a laptop.

How can I test my LAN speed?

LAN speeds can be influenced by several factors, including network hardware, device capabilities, network congestion, etc. You can use various tools to test the LAN speed, some of which are discussed below.

  • Transfer files between devices – One of the simplest ways to test local network speeds is to transfer files between devices on your network. Copy a large test file from one device to another and measure the transfer time, then divide the size of the file with the transfer time to get MBps.
  • LAN speed test tools – Use dedicated LAN speed test tools like iPerf, LAN Speed Test, or LANBench, which allow you to measure the transfer speed between devices on your network. They usually involve running a client-server setup, where one device acts as the server and the other as the client. The client device sends data to the server, and the tool calculates the speed based on the transfer time.
  • Network monitoring tools –  Network monitoring tools like ManageEngine NetFlow Analyzer and PRTG Network Monitor capture and analyze network traffic, allowing you to monitor bandwidth utilization, identify network congestion, and measure your LAN speed at different points in your network infrastructure.

What is typical LAN speed?

Ethernet networks have long replaced traditional LAN systems due to their superior speeds and reliability. Here are some common LAN speeds based on different network standards.

  • Fast Ethernet (100Mbps): The most widely used LAN standard, Fast Ethernet at 100 Mbps is found in older networks and home networks.
  • Gigabit Ethernet (1 Gbps): For handling higher data transfer rates than Fast Ethernet, Gigabit Ethernet is most commonly found in big home networks and modern office networks.
  • 10 Gigabit Ethernet (10 Gbps): This is typically used in more demanding environments such as data centers, large enterprise networks, or high-performance computing setups.

However, note that these are theoretical maximums, and the actual achievable speeds can be lower than this due to network congestion, cable quality, and other overheads associated with network protocols.

Final Thoughts

Measuring your local network speeds regularly can help you stay on top of potential network issues that might disrupt your experience. You can optimize your network infrastructure, troubleshoot problems, and ensure your network runs at its full potential.

To test network speed between two computers, you will need a LAN speed test tool that allows you to monitor different types of traffic entering and exiting your network. Make sure to go through the entire list to find a tool that matches your exact requirements.
