Re: [WISPA] UBNT Rocket M5 Throughput

[Tom DeReggi]

Can't rely on the noise level reading indicated on a live link's status screen. 
 (although we tend to put a lot of weight on the noise shown using the Spectrum 
Scanner over a period of time, paying attention to the peak value (blue line) 
). 
But even then, the results are shown as a single reading, and not individually 
for each polarity. What happens if one polarity is low noise and the other 
polarity has super high noise? 

For a noise free 2 mile ubiquiti link at 20Mhz, dual pol, we can actually get 
Iperf to push 70mbps. Although testing with devices/laptops attached tp ends of 
the radios.  So if you can only get 40mbps, something is wrong with the testing 
method or the link.

Heck, a 10mhz channel can push 35-40mbps with Iperf, at top modulation.. 
You could continue further by dropping down to 10Mhz, and seeing the rate of 
change. Also at 20Mhz, you have the flexibilty to change channels to make sure 
you aren't  centered on a bad channel.

What speed does the UBNT embedded speed test show? Note UBNT test is also based 
on TCP. On average our testing usally will see very simlar speed results 
comparing the UBNT built in test to Iperf. If UBNT test is also slow, you 
definately have a link issue. If UBNT test is much faster, then scrutinze your 
testing devices. Or play with Iperf to make sure its not the Iperf setting s 
you are using requiring tweaking.  Also, if using Iperf, try parallel streams, 
to see if you get a higher agregate throughput. That will tell you if it is a 
real capacity limit, or a TCP slow down issue due to quality.  It should be 
noted that the UBNT Rocket using it's embeeded test tool, can successfully 
perform a full speed test. I've tested up to 85mbps. So, to reduce variables, 
to trouble shoot a link problem, rely on the embedded test tool until such time 
that the embeeded tool can reach full speed. Once that is accomplished, you can 
scrutinize link quality further with Iperf.  The only need for Iperf is to test 
multi-hop to a non-UBNT end point, or parallel streams, to gather more data.   

We had an issue with Bullets not to long ago, where 5.3.3 firmware was super 
slow, but switching down to a 5.2 version solve the performance problem.
But that is not a Rocket. We've used later firmwares for Rockets fine, usually. 
  

When you push traffic does your modulation change frequently? or stay steady? 
Generally its good practice to leave radio set to a max mode equivllent to what 
it will stay at on average without downshifting.

if your link generally stays steady on a mode/modulation, and you are not 
getting throughput appropriate for that modulation, using the UBNT inbedded 
tests, its usually a timing thing, preventing the link from functioning 
optimally.  Manually stting the ACK time is one thing that is within your 
control to play with.  
When in doubt, if nothing makes sense, and you cant solve it, try changing 
firmware. Not only upgrade but downgrade. This has fixed our performance issues 
numerous times, even though a clear answer of why, was not determined.
  
What antennas are you using? Are they UBNT? If not, do they have a high enough 
port-to-port isolation? 

You also cant rule out multipath self interference, as with that you wont see 
noise if you aren't transmitting. You can try narrowing antenna beamwidth, if 
you aren't already.

  You probably either have 1) noisy channels, 2) incorrect ACK distances, 3) 
not optimal firmware version, 4) Or some third party factor effecting testing, 
such as testing devices that cant generate that much traffic or buffer sizes of 
routers.

   

  The first thing to try is switch down to 20mhz channel and see if the speed 
tests stays the same or higher, or if it drops proportionally. I bet the 20Mhz 
channel will perform better.

  Dont rely on CCQ on its own. Its one indicator, but does not mean you have a 
clean channel for sure.  Also remember, the Eth port is limited to 100mb, and 
if there is cable quality issues such as due to distance, it could autoadjust 
to half duplex. Test laptop to PC, isolating RF path, just for grins.  It is 
very rare to find 40Mhz of clean spectrum for Dual polarity, and even the 
slightest packet loss and delay can drastically reduce TCP throughput.

Are you testing with single-stream Iperf ou multiple-stream ? You need
multiple streams to stress such a link.
I would use Airmax off, fixed ACK for 2 mi just as you did.

Check also for duplex mismatches at one end or another. With large
packets I would expect to almost fill-up the Fast Ethernet, like twice
the performance you've got.

Re: [WISPA] UBNT Rocket M5 Throughput

[mike]

Shut them down and see if it makes a difference, on a site survey how hot does 
the UBNT gear see them? Some other things to look at the AMQ/AMC, the rates, I 
also like to look at the wifi0 stats for errors and athstats for subframe 
retries on the N-gear.

No, they recommend Airmax on for all links at this time, I think you have 
Airmax/NoAck entangled here. Be careful with Airmax as it's TDMA and doesn't 
handle co-location with other 5 ghz gear all that well, they tend to stomp on 
each other without shielding/separation (GPS should be a winner here).

Re: [WISPA] UBNT Rocket M5 Throughput

[Patrick D. Nix, Jr]

Is this the case even when you have good channel separation? I do have some 
other gear on the same tower but no overlapping channels.

No, they recommend Airmax on for all links at this time, I think you have 
Airmax/NoAck entangled here. Be careful with Airmax as it's TDMA and doesn't 
handle co-location with other 5 ghz gear all that well, they tend to stomp on 
each other without shielding/separation (GPS should be a winner here).

Problem is when I turn airmax on the speed really goes in the toilet. Best I 
can get is about 20mbps. According to ubiquiti airmax needs to be off up to 
15km links, anything over that airmax needs to be on. Do you have good success 
with short airmax ptp links?

Re: [WISPA] UBNT Rocket M5 Throughput

[mike]

Radio to Radio testing really isn't a good way to use iperf, part of the 
radio's resources are utilized for running iperf, you should test across the 
radio's not radio to radio. I have a backhaul that is hitting about 70 mbps 
nightly at the moment, it seems to perform well at 70 but I think I've only got 
another 10 (measuring across the link under utilization). I do use Airmax but I 
tend to use it only for loaded links as it keeps a more consistent response 
time when loaded, non-airmax tends to jitter under load, but when not under 
load it works better in my experience. Most of my backhauls are not Airmax 
enabled for this reason.

Hi Travis

what should be the expected throughput in your opinion?
