The first recommended LAN tool to test your Network performance is  HELIOS LanTest. This free-tool can work on Windows and MacOS. Indeed, it is a very popular network performance and reliability testing solution. However, this tool is so easy to use within seconds and scales from single local disk testing. It also can be used to evaluate the performance of a network volume as well as multi-user concurrent client testing against a single server volume.

HELIOS LanTest has been designed using the latest native APIs. Its design is to test common file I/O operations used when working with files on server volumes. To range from slower networks like standard Ethernet/DSL up to 40 Gigabit Ethernet, of course the five different setups are available. To use it, ensure to choose the proper network environment for the existing connection between client and server.

Here are the results of HELIOS LanTest that you can see on the screen:

Network connection Test File Size
Slow (Standard Ethernet/DSL) 3 MB (read/write/print)
Fast (Fast Ethernet) 30 MB (read/write/print)
Very fast (Gigabit Ethernet) 300 MB (read/write/print)
Enterprise (10 Gigabit Ethernet)


3000 MB (read/write)

2000 MB (print)

Backbone (40 Gigabit Ethernet) 12000 MB (read/write)

2000 MB (print)

How to get HELIOS LanTest? Well, to get it, you can download this tool through HELIOS WebShare  at You can type “tools” for username and password.

7–PassMark Advanced Network Test

This network benchmarking tool works with any type of TCP/IP connection. It includes cable modems, ADSL, dial up modems, ethernet, Wireless Networking (WiFi), Wide Area Networks (WAN) and Local Area Network (LAN). This tool actually has been optimized to use a minimum of CPU time that allows even high speed GB ethernet connections to be evaluated.

The PassMark Advanced Network Test is designed to test the data transfer rate between two computers which should be running PerformanceTest. In this case, one of the computers should act as the server and sit waiting for a connection. Meanwhile, the other computer roles as a client which connects to the server machine and sends data to it for the duration of the benchmarking.

By using this tool, you will have the ability to change some test parameters below!

  • The IP address of the machine roles as the server. The port number is used for testing to help with firewall issues.
  • The users can change the test duration.
  • The size of the data block can be changed for each send request. It’s possible to choose variable sized blocks to measure performance deltas as block size either increases or decreases.
  • The users can change the number of Test Threads.
  • The protocol either UDP or TCP can be changed. Change TCP Protocol is when data integrity is important. Then, UDP is definitely used with apps which are tolerant to data loss such as video streaming.
  • Change for Windows RIO (Registered Input/ Output API Extension) Socket Options.
