I've found that too. I've tried running iperf tests on my VDSL line with telkom as the ISP and it was broken and I've asked my friend on TTconnect with vox as the ISP to run iperf tests and they were broken too.

I can only assume CISP only let their clients run the tests or they've set them up in such a way that only work with their own clients.
Really? Mmmm, perhaps but I'm not convinced. I've run tests using my MTN LTE account with no issue. Also from another site using Telkom LTE.

IE... Telkom LTE, results are crap cause it's at best a 30Mbps line... The M value should have been around 25

I can't believe that's a real result. He NEVER has issues with his internet.

*EDIT he just tried again and got "Access is denied." Personally I don't trust any results that don't come from a cisp account, they always seem either wonky or outright don't work.

A transit provider will always prefer their transit service to a peer. But there are some work arounds. I'll have a look for you.
Almost 3 weeks later and it is still the same, are you actually doing anything about it or is this a waste of time waiting for something to happen?

He did post that the transit provider will change that will fix this for you...

Big changes like that takes time. Relax and enjoy the internet a bit too.

That test seemed to give weird results but this one below looks better i think
iperf3 --verbose --port 17001 -c queen.cisp.co.za --bandwidth 80M -l 1400 --omit 2 -R -u
Then this is displayed, although i never ever had speed issues no matter the time or day for international traffic

That test seemed to give weird results but this one below looks better i think
iperf3 --verbose --port 17001 -c queen.cisp.co.za --bandwidth 80M -l 1400 --omit 2 -R -u
Then this is displayed, although i never ever had speed issues no matter the time or day for international traffic

I think he's never seen the bandwidth parameter before.
What are you saying?
No, I'm familiar with how the bandwidth parameters work. My line is 1Gb so technically I should be able to go close to 700M but it maxs out for me around the 500M mark.

The reason I'm so intrigued by it though, is because on the iperf3.exe -R -u -b xxxM -p 17001 -c queen.cisp.co.za test it's totally out of whack when the M value is anything higher than 12M. The answer to my iperf anomaly woes are contained within these results. Just need someone with the political will and technical prowess to assist me.

Of course I have no idea what the iperf3 --verbose --port 17001 -c queen.cisp.co.za --bandwidth 500M -l 1400 --omit 2 -R -u command is actually testing. I run the iperf tests without having a clue what they actually testing and what the results mean. Just that the percentage loss at the end of the tests needs to be as close to 0% as possible.

My understanding of the switches are. Verbose, detailed readout. Port, self explanatory. c, specify which server to connect to. Bandwidth, again self explanatory. Omit 2, ignore the first two results on the summary line since they're usually inaccurate. R, reverse mode so you receive data from the server instead of sending it. u, means test udp instead of tcp. l, I think is buffer size.

If you want a more general overview of what iperf does. Its a detailed readout of the throughput on your line. Imagine doing a speedtest for 10 seconds but every second that speedtest is happening you are being given how much loss there is, what the transfer rate is, what the jitter is, how many packets were pushed and whether they were in order or not.

I stand to be corrected but that's my understanding of what iperf is. Hope it helps.

If you do a local speedtest what results are you getting on your 1GB
