Iperf 3.21 Windows build

[+BudMan MVC]

So there has been an on going thread about powerline adapters, well the OP finally got some - and I was curious about speed he is seeing, etc.  So told him would post up links to some tools.

 

This lead me to compiling the latest version of iperf3 I could find for windows Since I couldn't find one.  So figured post it up if anyone is interested.

 

Got the source from here https://github.com/esnet/iperf

Found a blog post how to compile on windows here http://www.embeddedsystemtesting.com/2014/08/how-to-compile-iperf3-for-windows.html

 

So few minutes later I end up with a copy of the current iperf3 that works on windows.  Needs a few cygwin dlls, included in the zip.  But other than that unzip and go.

 

It has lots of new options compared to the older versions

 

Been a fan of iperf for years, so will prob keep this current when new versions come out since doesn't seem like anyone else is posting up the windows builds, etc.

You can grab all my compiled versions here https://files.budman.pw/

Any questions on its use, just ask -- post up some tests as well!!

 

edit: updated this on 02/25/17 new build 3.1.6

http://software.es.net/iperf/news.html#iperf-3-1-6-released

This version of iperf3 contains two minor fixes. Notably, one of them unbreaks JSON output with UDP tests.

 

edit2:  5/23/17 Thanks to @Datalink for letting me know site was down.  Back up now, if your having issues flush your dns had to move it to different host.  Added site to my monitoring so next time it goes down will know right away

BTW 3.1.7 just typo's so no reason to compile it

2017-03-06: iperf-3.1.7 released

This version of iperf3 contains two documentation fixes, but is otherwise identical to the prior release.

iperf 3.10.1 fixes a problem with the configure script that made it make not work correctly in some circumstances. It is functionally identical to iperf 3.10.

I didn't seem to have any issues with my 3.10 build, but redid to keep with current version numbers.

[Roger H. Veteran]

Sweet stuff! (y)

 

I'll start testing my powerline stuff too (TP Link TP6030s - same as the 6010 but with 3 x 1Gbps ports on each device). My Xbox, TV and WDTV will be connected to it so need to make sure it can handle it all! :yes:

[+BudMan MVC]

It would be very interesting to get some powerline adapter real world numbers sure..  The one's the OP got show 500mbps, but wireless makers say that new router is 450mbps 2.4, which will all know is a crock of sh_t!

 

I have noticed couple of things not working on windows with this build, the zerocopy -Z is not supported, that is kind of a given.  But the -J for json output causes a stackdump as well, so don't use those ;)

 

I keep meaning to grab a set to play with, but then again I run wire if needed ;) I have set them up in a few places..  But no gig, and they easy do 100mbps without any issues..

[Roger H. Veteran]

Get the TP-Link TL4010 kit, like $30 on Newegg and gave me 10MB/s* copy speeds between my laptop and the NAS connected to a 1Gbps switch. They were also in the same room, same outlet even so not "normal" usage but just wanted to get a general idea of what they are capable of.

 

* - Note the 4010 one is limited to a 10/100 port so the speeds were limited there. The 6010 pushes ~40MB/s in the same setup with a link rate of 337Mbps. Didn't try to do more testing to see if it could be faster but figured that's pretty good.

 

I'll do some real testing on the weekend :D

[+BudMan MVC]

where do you see a link rate?  40MBps is best you can hope for with that rate..  Simple /8 math gives you ballpark numbers 337/8 = 42.125 ;)

[Roger H. Veteran]

Yeah, no got that, I was expecting a full 500/600Mbps link rate however since they are right next to each other.

 

Doesn't matter much I guess, was just a quick test :)

 

The software for it shows the link rate:

 

Took this shot from http://www.smallnetbuilder.com/lanwan/lanwan-reviews/32454-tp-link-homeplug-head-to-head

 

 

The software is not super useful but It does allow some little tweaks ("QoS" - dunno if it actually works) along with firmware upgrades.

 

 

 

[+BudMan MVC]

Well the link rate is good info to know, so software is useful for that and firmware updates.. So looks like the link rate it reports is pretty close to the money then which is good validation with your file copy.

So does the software pick up the other device on the other end of the powerline connection or do you have to plug in on that side to see that one?

[Roger H. Veteran]

The software on the Network tab will show you details of the other devices you have plugged in. In my case I have 4 so 3 show up on the Network tab. To see the info of the local one you have to plug into it or something connected to it which would show on the Status page. Doesn't show much info though, you can just change the Network name and view the password as seen below:

 

 

Here is the advanced tab if you were curious:

 

 

So basically I just use it to test/setup and then get rid of the software.

Updated build

New Version is out iperf3_10 http://software.es.n...3-0-10-released, I have updated the windows build you can find it here

http://files.budman.pw/iperf3_10.zip

md5 of zip 7DF9AF051A5554DC342DE366710FFC35

using current version of cygwin dll 1.7.33

Quick test shows its working fine, anyone find any problems let me know.

[+John Teacake MVC]

Cool! I am running on some of the very first home plugs, They work well for me at the minute but I should really upgrade to Gig ones at some point. Been meaning to for a while. I guess I am waiting for the right "deal" .... They work fine for my web browsing but transferring large files around not amazing but do the job.

[remixedcat]

I got AV600 ones and I see around 8-12MBytes/sec transfer and they are NETGEAR

[+BudMan MVC]

So I just got a pair of these that someone was not using any longer, and they are the netgear AV500 model (XAV5201 - but WTF they only have a 10/100 nic -- how and the F can they get away with the 500mbps label.. I thought it was nonsense when wifi spouts out their nonsense numbers.. If you want to call them 200mbps when you have 100mbps full duplex But 500 come on give me a break.

Figured could do some testing, but kind of pointless with limit of 100mbps interface.. But yeah better than wireless connection.

[Praetor]

thanks budman for the update of the compilation.

Backplane speed

[+BudMan MVC]

Backplane speed my ass - they come in a kit with 2 of them.. Now maybe the 1 that has 4 ports on it

And even if it could do 10 freaking trillion bps doesn't matter when you have 2 of them and connecting with it 100mbps nic..

Come on companies - why not just print actual freaking numbers the users can expect!!

[remixedcat]

it's a ______ contest -_-

[+BudMan MVC]

Yeah I understand wanting to say your the fastest, etc.. How about actually being the fastest with actual real numbers and benchmarks, etc

[remixedcat]

yeppers and most can't even come close.. like ac1200 only gets 300Mbps or around 36-42MBytes/sec

[+BudMan MVC]

They add up numbers that don't reflect what can be seen by the client.. A 1750AC router for example adds the 2.4 and the 5ghz together, even though no single client can use both together.

Are you connecting at 1200 as you phy data rate reported by the client? If so 300 is bit low.. Other problem with speeds reported these days, which I can understand is the AP numbers - you have 3x3 at the AP, but then you connect with single stream client, your not going to see anywhere close to what it might do if 3x3 client.

[+BudMan MVC]

Updated to build 3.11

 

This maintenance release adds a -1 flag to make the iperf3 execute a single test and exit, needed for an upcoming bwctl release. A few other bugs are also fixed.

 

D:\iperf3_11>iperf3.exe -v
iperf 3.0.11

 

Server specific:
  -s, --server              run in server mode
  -D, --daemon              run the server as a daemon
  -1, --one-off             handle one client connection then exit

 

Updated first post with link to new file.. Also cygstdc++-6.dll does not seem to be needed, so removed it from the zip.

Thank you for compiling iperf3 for Windows!

 

It's working but I had to jump through some hoops. Specificallly, it won't work if I leave iperf3.exe and the dlls in the same folder, even if I add the path to this folder to the Path environment variable. I had to move the dlls to a different folder, and add it to the Path environment variable also.

 

Now everything is working great, I just wanted to share in case somebody runs into the same problem.

Yeah I understand wanting to say your the fastest, etc.. How about actually being the fastest with actual real numbers and benchmarks, etc

Happy Birthday!

New Version is out iperf3_10 http://software.es.net/iperf/news.html#iperf-3-0-11-released I have updated the windows build you can find it here

http://files.budman.pw/iperf3_11.zip

md5 of zip e58f2721f70f43e78a1c9ae8605dd025

using current version of cygwin dll 1.7.33

I pulled out one of the cygwin dlls - doesn't seem to be needed.

 

Hi

First of all grate work thank you!

 

Little fix to your post, if you hover over the link http://files.budman.pw/iperf3_11.zip you will see it actually redirects to version 3_10 the hyperlink needs to be fixed

 

 

Also if you run the command with the Json switch it crashes, for example:

iperf3.exe -s -J
      0 [main] iperf3 3004 cygwin_exception::open_stackdumpfile: Dumping stack trace to iperf3.exe.stackdump

Do you have any idea how we can fix it?

 

Thank you

thanks for the input will take a look at my links, and look into that crash..

edit: ok link updated - that was issue with editor on neowin, once I changed to see the code then yeah saw that popup was wrong. Thanks it has been corrected. Now just to take a look at the crash

 

edit2:  So far have not been able to get this -J working, I get the same crash.  I found some old patches to run compile on windows under cygwin.  I applied them, and seems to still work - but still get crash if -J, what is odd is works under cygwin.  Not just if you try and run with the .dll

 

I have updated cygwin to latest build, and moved to 64 that got rid of another dll requirement when you run cygcheck..  Need to do some more playing.  Not a huge coder, I can make minor changes, and can follow a long if someone is going over something.  But diving in and looking for something like this from scratch is a bit over my skill set.  But since it works when run inside cygwin, the Exception: STATUS_ACCESS_VIOLATION points me to maybe something in permissions.  Lots of talk of rebase when getting that error..

 

And just noticed post about having to move the dlls?  Where exactly are you having to put them?  Clearly that is not the case on multiple machines I have run the files on.  Do you have the cygwin dll somewhere else in your path?  Do you have cygwin installed?  Will update any more info I get.. For now guess don't use -J or run it under full cygwin if you need that option on a windows box.  I tried it as well on the linux builds and those are fine for -J.

I created a little GUI for iperf in Powershell for learning purposes in my free time

You can chack it out here https://github.com/ili101/PPerf

 

This is what I wanted the -J option for
