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. My mac says more storage from apps. 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

↓ 03 – TamoSoft Throughput Test | Windows | macOS
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. https://famousyellow.weebly.com/mac-hardware-test-software-download.html.
- 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.

The read speed test is flawed as written. Using /dev/zero as dd's input and output file doesn't hit the disk at all and will return ridiculous speeds like 15-20 GB/sec. The proper way to do the read test is to be to dd the tstfile created by the write benchmark into /dev/null (but only after clearing the RAM cache by using the 'purge' command).
This one-liner will test the write speed, clear the cache, properly test the read speed, and then remove tstfile to reclaim disk space:
dd if=/dev/zero bs=1024k of=tstfile count=1024 && purge && dd if=tstfile bs=1024k of=/dev/null count=1024 && rm tstfile
Here's what I get using this method (and dividing by 1048576 to get Mb/sec):
Internal laptop hd (7200 rpm, sata): Write=42.99 Mb/sec, Read=38.09 Mb/sec
External G-Raid (esata): Write=134.76 Mb/sec, Read=192.32 Mb/sec
External Seagate hd (laptop drive, USB-2): Write=33.59 Mb/sec, Read=36.38 Mb/sec
External G-Raid (Firewire 800): Write=60.79 Mb/sec, Read=66.17 Mb/sec
Encrypted sparsebundle image on external G-Raid above (esata): Write=68.66 Mb/sec, Read=81.33 Mb/sec
That's not really very fast for Thunderbolt.
I bought a Factory Refurb LaCie Little Big Drive for $229 (LaCie.com), removed the drives and the fan, and replaced the drives with a pair of SSDs. Using RAID0, I get around 450MB/s read and 360MB/s write speeds with every test I've tried. It's much faster than the internal SSD in my 2011 iMac.

Yes, the WD My Book is a bit slower, but it has no fan, which is a big plus. I wonder, though, if I should be getting higher speeds. Oh, BTW, I'm not using RAID 0. I'm using mine as two 2 TB disks. That cuts the speed in half. Mac OS X Hints editor - Macworld senior contributor

The freeware Xbench's Disk Test offers a nice method for getting a few different kinds of disk benchmarks.
i.e: and No need to google around. Also keep in mind it's only as fast as your system's slowest bottleneck. I realized this myself when I recently upgraded my internal HDD to SSD. Obviously I didn't do proper research. I got a top of the line model and was expecting super fast speeds around 460MB/s on SATA-III, only to realize that my 2008 MBP only has SATA-I so I get about 120 MB/s.
Probably still faster than HDD, but I never did measure the speed before I upgraded.
Magic bullet suite 12. You wouldn't save a great deal of money going sata-I or II ssd and this way you are future proof if you'll get a new mac.

That awk line has an extra quote, it appears.
Any way, I found that this works:
time dd if=/dev/zero bs=1024k of=tstfile count=1024 2>&1 | grep sec | awk '{print $1 / 1024 / 1024 / $5, 'MB/sec' }'
You don't need bc at all, awk can do the arithmetic. I am dividing the total bytes by the total seconds and by
By the way, my standard internal drive in my 27' iMac (2.8GHz, a couple of years old) did the writing at 91 MB/sec.

Even better, leave out grep also. Awk can do its own pattern matching:
time dd if=/dev/zero bs=1024k of=tstfile count=1024 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'
Mac Os X 10.13
One additional thing that might be worth mentioning.your test file (tstfile) should be larger than the amount of physical ram.
This prevents caching and artificially inflated read speeds. Allow me to demo this on my snazzy new iMac with the PCI-e drive.
The system has 16GB of ram, a 3.5 GHz i7 and 512 GB PCI-e SSD:

2GB, way less than 16GB.
Now lets Read it back.

Mother of God!! 6.2 GB/sec!!
Hmmm.that can't be right.
So lets try a much larger test file.
NOTE: The file size does not *need* to exceed your total ram, just the amount you have free. If you feel this is a valuable use of your time ;) hint, hint -- then adjust block sizes and counts to just exceed the amount of free memory you have available.
Here Goes with a 16GB file:
madht@host (]> 01:30:44

Still bloody fast writes, yum.

madht@host (]> 01:42:45
~>ls -al tstfile

Yep, that one there is a whale that can't be crammed into my ram.
madht@host (]> 01:42:49
~> time dd if=tstfile bs=2048k of=/dev/null count=8192 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'

real 0m21.018s
user 0m0.006s
sys 0m4.323s
Aaaah much more like it. And still pretty performant, yo.
One more thing to add and I don't know if was already mentioned or not tl:dr -- this is a sequential test only. iow - this is as fast as it gets and in no way indicative of how your drive performs when ~30-50% of its reads and writes are random - i.e. during regular multi application usage of the OS. ioMeter is the best open source benchmarker out there however they don't fully support OSX, just the worker engine binaries -- so iometer itself would have to run on a separate machine. But it's doable ;)
Would anyone be able to tell me how to use these commands to test my USB 3.0 drives or Thunderbolt drives?
