Understanding and Troubleshooting Network Performance
Computer networking is a complex topic. In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking.
If you just need to know how to perform a network performance test/benchmark, jump down to configuring iPerf.
Core Network Concepts
LAN vs WAN
With regards to network performance, it is crucial to first separate whether an issue is with Wide Area Network (WAN) performance, or if the issue is with Local Area Network (LAN) performance.
Your LAN is essentially the network inside your home or business. Many homes use a combination modem/router device provided by their Internet Service Provider (ISP). In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. The connection your modem makes to your ISP is the WAN, and any devices you connect through your router behind that modem belong to the LAN.
Link Rate
Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind. The link rate establishes how fast data can possibly be transferred across any given connection, but it does not guarantee how fast the hardware on either end of the connection will actually transfer data.
The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
- 800Mbps—The file source is a USB 3.0 thumb drive capable of 100MB/s (800Mbps) read/write.
- 480Mbps—The USB 3.0 thumb drive is plugged into a USB 2.0 port on the PC, which has a maximum throughput of 480Mbps
- 1000Mbps—PC1's Ethernet connection establishes 1Gbps (1000Mbps) link to the router via Ethernet
- 300Mbps—The router connects to a second PC (we'll refer to this as PC2) via Wi-Fi, and it has established a 300Mbps link to the Wi-Fi adapter on PC2
- 480Mbps—The Wi-Fi adapter on PC2 is connected via a USB 2.0 port. The link rate of the USB connection to PC2 is at 480Mbps
- 6000Mbps—PC2 is going to store the file on an internal hard drive with a link rate of 6Gbps
- 1600Mbps—File Destination: SATA hard drive capable of 200MB/s (1600Mbps) read/write.
Following this chain, we see that 300Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is 300Mbps.
if we were to change the Wi-Fi connection to a wired Ethernet connection capable of 1Gbps, our performance bottleneck would then become the USB 2.0 connection to the USB drive where the file is stored.
Ports and Interfaces
Interfaces
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
Ports
Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports". Each network interface has 65,535 of these logical ports. Each port on a network interface is a separate data connection.
Benchmarking Network Adapter Performance
To properly benchmark network adapter performance, we need to:
- Use a simple LAN configuration
- Eliminate bottlenecks, especially link rate bottlenecks
Websites like speedtest.net, fast.com, and other performance tools in your web browser are going to use your WAN connection, and are not appropriate for determining if a network adapter is working well.
Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf . To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
Configuring iPerf
To test a connection using iPerf, you'll need at least two network interfaces, and preferably two computers. You'll also need to know the IP (Internet Protocol) address assigned to each network interface . One network interface will function as an iPerf server, and the other network interface will function as an iPerf client. Lastly, you'll need to download the version of iPerf 3.x that's appropriate for your computer's operating system and extract/install it .
Windows
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers. Drivers for Plugable products can be found here.
- Download and extract iPerf for Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The
cdcommand is for 'change directory'- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in server mode via Command Prompt
iperf3.exe -s
macOS
- Usually it is best to install iperf on macOS using brew in Terminal
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Linux
- Usually it is best to install iperf using the package manager in your Linux distro. For example, in Ubuntu, use
apt: sudo apt install iperf3
- Make sure the drivers for both network interfaces involved in the test are using up-to-date Drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Next, you'll need to run iPerf in client mode, targeting the IP address of the server/interface where iPerf is running in server mode. Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The

cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in client mode via Command Prompt (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3.exe -c 192.168.0.200 -t 30 -P 4
macOS / Linux
- Open Terminal
- Run iPerf in client mode (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3 -c 192.168.0.200 -t 30 -P 4
iPerf should start performing a network performance test. If the test fails to start, make sure that iPerf is not being blocked by your PC's/Mac's firewall.
Why iPerf is Ideal for Benchmarking
Unlike a file transfer, iPerf runs in memory on the PC and generates data to send using the CPU directly. This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means.

Maximizing 2.5Gbps Ethernet Performance
Ethernet technology has come a long way since its inception in the late 1970s when early Ethernet operated at 10 Mbps, which was considered fast for its time. As digital demands increased, so did the need for faster data transfer speeds, leading to the introduction of Fast Ethernet (100 Mbps) and eventually Gigabit Ethernet ( 1 Gbps ), which has been the standard for home and office networking for over 20 years. Over these years, Ethernet continued to evolve, with standards being developed to handle even higher speeds but most often being isolated to the server room, and cloud computing. Today, technologies like 2.5 Gbps and 5 Gbps Ethernet have developed from 10 Gbps Ethernet, catering to modern high-bandwidth applications in both home and office environments. These advancements make it easier than ever for users to connect and transfer data at speeds that support the demands of video streaming, gaming, and extensive network tasks with higher reliability and lower latency than WiFi.
Upgrading a whole network from Gigabit to 2.5Gbps or faster can be costly and time consuming, but it doesn’t have to be done all at once. We have released both 2.5Gbps and soon 5Gbps USB Ethernet adapters that can be used with both notebook computers and desktops to provide up to five times faster Ethernet speeds than the built-in network controller, without having to install any new PCIe cards. Both of our high-speed Ethernet offerings are backwards compatible with current Gigabit Ethernet and in many cases can use the same network cables, however we do recommend replacing Category 5 and Category 5e cables with at least Category 6a or Category 7 cables to ensure future compatibility with both 5Gbps and 10Gbps Ethernet. Desktop 2.5Gbps and 5Gbps Ethernet switches are also coming down in price and can be used to quickly upgrade the network throughput between nearby computers.
As you make the upgrade process there are some steps that can be taken to ensure the network throughput is maximized between the 2.5Gbps or faster computers.
Maximizing 2.5Gbps Ethernet Performance
Maximizing the performance of a 2.5Gbps Ethernet network can enhance both speed and reliability, especially for power users who value efficiency and seamless connectivity in a busy IT environment or at home for the fastest home media center. Here are some best practices for small 2.5Gbps and 5Gbps network setups:
Upgrade Network Infrastructure for Compatibility
Switches and Routers: Ensure your network infrastructure, particularly switches and routers, supports 2.5Gbps or 5Gbps Ethernet. Many older devices are limited to 1Gbps, which will bottleneck the system.
This is most important between the computers that need the higher speed, if you have internet speed at or below 1Gbps then upgrading the router will not improve performance, so long as all computers that need faster local area network access are connected to the same 2.5Gbps or faster Ethernet switches.
Cable Quality: Use high-quality Cat 6a cables or better. While 2.5Gbps is designed to work with Cat 5e Ethernet cables, at least for short distances, for longer runs and to ensure the best performance Cat 6, 6a, or Cat 7 are recommended for 5Gbps networks.
Optimize Device Connections and Settings
NIC Configuration: Adjust your network interface card (NIC) settings to ensure optimal performance. This may involve tweaking parameters such as jumbo frames or flow control for maximum efficiency.
Ethernet data frames with more than 1500 bytes of data are called “jumbo frames”. Setting a larger frame size packs more data into each frame and can potentially reduce the CPU overhead, however to function it must be enabled on both endpoints and supported by all networking hardware in between. For most users there will be no noticeable difference in network performance, however in some specific cases like when a home server is transcoding and streaming video it can help to reduce the CPU overhead of the entire process. This can best be enabled on short point-to-point networks rather than sprawling networks, as packet loss with jumbo frames enabled causes significantly worse slowdowns than with standard frame sizes.
Flow control allows for the receiving system to transmit a pause request to the transmitting system to prevent data loss. This is necessary when multiple computers are communicating to the same server as there is generally not enough bandwidth to service all requests simultaneously, however it can be disabled in a point-to-point network setup where both computers are directly connected and both computers can handle full-speed data throughput. QoS - Quality of Service offers an alternative to Flow Control but requires significantly more setup often including managed switches and may not be an effective choice for the home and small office networks.
Driver and Firmware Updates: Keep all drivers and firmware updated for your network adapters, switches, and routers. This reduces potential compatibility issues and improves performance. Firmware updates are also important for maintaining network security, vulnerabilities in router firmware have been historically exploited to create network back doors, to exfiltrate data, as well as creating bot-nets for DDoS - Dedicated Denial of Service attacks on websites.
Drivers for Plugable devices can be found on our product pages, under the "Downloads" tab.
Consider Network Segmentation
For a network with mixed-speed devices (1Gb, 2.5Gbps, 5Gbps and 10Gbps), segmenting traffic can prevent slower devices from dragging down performance. This can be done physically by using gigabit Ethernet switches separate from 2.5Gbps or 5Gbps switches then bridging the switches together, or virtually by setting up virtual LANs (VLANs) with a managed Ethernet switch. VLANs can help allocate 2.5Gbps and 5Gbps connections exclusively for high-bandwidth tasks while lower speed devices can utilize secondary gigabit Ethernet ports on the server or client computers.
Leverage Multi-Gig Capable Devices for Key Applications
Identify the devices that will benefit the most from 2.5Gbps and faster connections, such as NAS - Network Attached Storage systems with integrated 2.5Gbps or 5Gbps Ethernet, high-performance workstations or desktop replacement notebooks with USB Ethernet adapters, or servers with multi-port bonded Ethernet controllers handling large data transfers. Connect these devices directly to a switch that can take advantage of the higher network throughput to ensure they receive the best performance possible.
Future-Proofing with 2.5Gbps-capable or faster Docking Stations and USB Ethernet Adapters
Many Plugable docking stations now support 2.5Gbps Ethernet, which could be ideal for enhancing productivity for hybrid work setups, at home, or in the classroom by enabling high-speed, wired connectivity. Plugable’s docks also simplify integration across Windows and Chrome OS devices, which can be especially helpful in mixed-device environments.

How Can I Check the Ethernet Adapter Link Rate on my Mac?
One helpful way to identify your ethernet link rate speed is through the System Settings app in macOS. This can help us identify if your Plugable ethernet adapter is negotiating either 1Gbps or 2.5Gbps network speeds. Some routers have a mix of 1Gbps or 2.5Gbps ports, and in the macOS System Settings this will be shown in the Speed field.
In this example, we will be analyzing our USBC-E2500, which is a 2.5Gbps ethernet adapter. This method applies to all of our ethernet adapters, such as:
Navigate to the Network section, select the entry named “USB 10/100/1G/2.5G LAN” with the Green - Connected icon. Expand the Details button, and go to Hardware.
In the field that says Speed, you should see 2500Base-T if the ethernet adapter is connected to a 2.5G ethernet LAN port on your router. If you see 1000Base-T, this means the adapter is connected to a 1G ethernet LAN port. If you are expecting faster network speeds, please see your router's documentation on its multi-gig LAN port.
