How to test internal LAN network speed? In order to test and troubleshoot networks we need tools that allow us to generate network traffic and analyze the network’s throughput performance. This is true for both wired and wireless networks. In order to properly troubleshoot a wireless (or wired) network we need a way to benchmark its performance, so as modifications are made we can determine whether or not they really make a difference in the network’s performance.

This is where these LAN benchmarking tools fits in to test network speed between two computers. The concept is you install a new wireless network and it works perfectly. Run these tools and record the benchmark results for later reference. Sometime in the future when either you or others suspect performance has declined then run these tools again and compare the latest results with those you gathered when the network was first installed and working perfectly.

↓ 01 – LAN Speed Test Lite | Windows | macOS

LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless). First, you pick a folder to test to. This folder can be on a local drive or USB drive, etc. to test the drive speed, or a shared folder on your network to test your network speed.

Next, LAN Speed Test builds a file in memory, then transfers it both ways (without effects of Windows/Mac file caching) while keeping track of the time, and then does the calculations for you. For more advanced users, you can test to LAN Speed Test Server instead of a shared folder to take the slower hard drives out of the process as you are testing from one computer’s RAM to another computer’s RAM. Simple concept and easy to use. You’ll find that LAN Speed Test will quickly become one of your favorite network tools!

• Test the speed of your Local Network by testing to/from network shared folders
• Test the speed of your local drives (USB Drives, hard drives, etc.)
• Compatible with LST Server (v1.5 or later) for real network performance results without hard drive limitations – Even test your WAN (Internet) speed with LST Server
• Ability to choose Network Interface Card for computers with multiple NICs

↓ 02 – HELIOS LanTest | Windows | macOS

HELIOS LanTest is a very popular network performance and reliability testing solution for Mac and Windows clients. It is very easy to use within seconds and scales from single local disk testing, to testing performance of a network volume, as well as multi-user concurrent client testing against a single server volume.

TamoSoft Throughput Test is a utility for testing the performance of a wireless or wired network. This utility continuously sends TCP and UDP data streams across your network and computes important metrics, such as upstream and downstream throughput values, packet loss, and round-trip time, and displays the results in both numeric and chart formats. TamoSoft Throughput Test supports both IPv4 and IPv6 connections and allows the user to evaluate network performance depending on the Quality of Service (QoS) settings.

Microsoft Windows: Windows 7, Windows 8, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2. Mac OS X: Yosemite (10.10), El Capitan (10.11), Sierra (10.12), High Sierra (10.13), Mojave (10.14). Android (client only): Android 4.1 and newer. iOS (client only): iOS 8.0 and newer.

↓ 04 – LANBench | Windows

LANBench is a simple LAN / TCP Network benchmark utility. It is designed for testing network performance between two computers and is based on Winsock 2.2. LANBench tests TCP performance only and is designed for minimal CPU usage so that the pure performance of your network could be fully tested.

• Multiple simultaneous connections – up to 20 (for load simulation)
• Low CPU overhead for pure network performance test
• Multithreaded utilizing Windows I/O completion port
• Configurable packet size, test duration and transfer mode

↓ 05 – NetIO-GUI | Windows

NetIO-GUI is a Windows frontend for the multiplatform commandline utility ‘netio’. It measures ICMP respond times and network transfer rates for different packet sizes and protocols. All results are stored in a SQLite database file and can easily be compared. NetIO-GUI is preferred to rate the quality of peer-to-peer connections like VPN.

↓ 06 – NetStress | Windows

NetStress allows you to generate network traffic and analyze the network’s throughput performance. The results of that comparison with previous benchmark will indicate whether or not there really is a problem and dictate which steps to take next (if any). Regardless of your technical expertise or how expensive your diagnostic tools, if you are modifying a wireless network or making decisions to modify it and you are not testing throughput then you risk wasting time and resources going down the wrong path.

• Single instance of the application (i.e. each instance can be used as server or server plus client)
• Supports both TCP and UDP data transfers
• Supports multiple data streams
• Variable TCP / UDP segment size
• Rate of packet transmission (Packets Per Second)
• Variable Maximum Transmission Unit (MTU)
• Uplink and downlink modes
• Auto node discovery
• Choice of display units (KBps, Kbps, MBps, Mbps)
• Support for multiple network adapters

↓ 07 – iperf | macOS | Linux

iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters. The current version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR/DAST.

iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is not backwards compatible with the original iperf.

↓ 08 – PassMark Advanced Network Test | Free Trial | Windows

The network benchmark test will work with any type of TCP/IP connection. Including ethernet, dial up modems, ADSL, cable modems, local area networks (LAN), Wide area networks (WAN) and wireless networking (WiFi). The software has been optimized to use a minimum amount of CPU time, allowing even high speed gigabit ethernet connections to be benchmarked. Users have the ability to change the following test parameters.

• The IP address of the machine acting as the server and the port number used for the test to help with firewall issues.
• The size of the data block used for each send request. It is also possible to select variable sized blocks to measure performance deltas as block size increases or decreases.
• The duration of the test.
• The protocol, either TCP or UDP. The TCP protocol is when data integrity is important (Errors are corrected using data re-transmission). UDP is used with applications that are tolerant to data loss such as video streaming.

HELIOS LanTest performance vs. Finder/Explorer copy performance

When copying large files from and to the server with Mac OS X (AFP) or Windows (SMB) via the Mac Finder or Windows Explorer, copying may be significantly faster compared to the HELIOS LanTest UB64 read/write results. This has two reasons:

Mac Finder copy block size

The Mac automatically increases the Finder copy read/write block size up to several megabytes, until there is no additional performance gain, and continues with the most stable performance. This is a dynamic process and the Finder does a great job. HELIOS LanTest uses a static block size during the entire test depending on the selected network speed, e.g. for Gigabit networks it uses 128 kByte buffers. The HELIOS LanTest approach is more realistic because no application uses a dynamic adjustment and there is no API doing so automatically. Another reason is that HELIOS LanTest should measure the network performance and the server latency and doing super large block sizes would not include the server latency. Network and server may be capable to offer additional performance when multiple threads are reading/writing in parallel and when super large blocks are being used. However, this is not realistic because it causes drawdowns on slower network connections and limited network switch buffering as well as limited socket I/O buffers on the server and client.

HELIOS LanTest comes much closer to real client/server environments and measures the true performance, including the latency.

HELIOS believes that these block sizes are realistic and represent typical use cases.

Windows Explorer CopyFile behavior

Starting with Windows 7, customers experience very fast copy speeds to and from the HELIOS PCShare file server. Microsoft internally optimized the CopyFile API which does up to eight asynchronous reads or writes in parallel, each of 32 kByte size. This feature is only available with the CopyFile API or doing asynchronous reads and writes in parallel, e.g. with multiple threads. The new CopyFile is an improvement for SMB servers when clients copy files using the Explorer or the CopyFile API. HELIOS LanTest measures the performance with sequential read/write operations using a specified block size, e.g. 128 kByte using Gigabit Ethernet testing. This reflects much better how applications work because it is very unlikely that applications use multiple asynchronous I/O requests in parallel. Depending on the network, client and server performance in a LanTest measurment of a 1 Gb network may get around 60 MB/sec reading and writing, the Windows Copy file may get around 100 MB due to multiple asynchronous I/Os.

Jumbo Frames – Ethernet MTU (maximum transfer unit)

By default,lower level TCP/IP packets are 1500 bytes large which is the standard for all servers and clients that are available today. Using Gigabit Ethernet and newer, MTU sizes up to 9220 bytes are allowed. MTU sizes larger than 1500 highly depend on the settings of the network NIC, Network Switch, VLAN, and layer 3 routing capabilities, as well as client and server OS settings. Larger MTU sizes can also result in failing TCP/IP connections and must be tested and enabled with care. Often a dual network interface config is suitable, e.g.: 1 GB Ethernet for standard services and Internet use, and in addition a 10 GbE Interface with Jumbo Frames from the client directly to the server for dedicated performance reasons, e.g. video editing, file syncing, etc.

Server and network latency testing

To measure the latency between the LanTest client and the server, run the “Lock/Unlock” test. As recording locking is based on many little 10 byte lock requests (forty rotating concurrent locks are being used) it does not involve any disk I/O. The HELIOS EtherShare and PCShare server implementation uses a shared memory for locking and there is no waiting operating system API involved. This means the locking test performance depends only on network speed, TCP/IP performance, server process scheduling, and finally the client OS with its network re-director. If latency is high, “Lock/Unlock” testing takes forever and investigation in the source of the performance problem is needed. Using different network connections, e.g. a cross-over cable between client and server, or different clients, or a different server allows isolating the problem. The LanTest latency testing is perfect because it omits any disk I/O and allows end-to-end client/server testing.

Summary

There is a race between Microsoft and Apple, with both vendors enhanced Finder/Explorer file copy usage within several releases. This works great against HELIOS servers and brings an even greater performance with EtherShare (AFP) and PCShare (SMB1). (SMB2 is still in development at HELIOS and not ready for production.) HELIOS LanTest offers true performance results and reflects how 99% of applications access files on server volumes. The HELIOS LanTest testing procedures are identical on Mac and Windows clients. LanTest also turns off client side caching to ensure that it represents end-to-end performance between the client and the server, including disk I/O, TCP and network NIC performance, as well as process task switching latency. HELIOS LanTest is perfect for file server performance measuring and reliability testing.
