iPerf3 Testing Assistance Needed - Troubleshooting throughput with ISP

Hello,

I am wondering if anybody would be so grateful to do an iPerf3 test to a public server that we setup and post the results? Here is what I am hoping you can provide.

  1. Your Location
  2. Your ISP and speeds you are paying for (up/down)
  3. Average Upload iPerf Results
  4. Average Download IPerf Results

You can download iPerf here

https://iperf.fr/iperf-download.php

Upload Command

- PowerShell - "./iperf3.exe -c 209.59.236.70"

- cmd - "iperf3 -c 209.59.236.70"

Download Command

- PowerShell - "./iperf3.exe -c 209.59.236.70 -R"

- cmd - "iperf3 -c 209.59.236.70 -R"

The reason I am requesting this is to compare the results and share with the ISP.

It's a long story but basically we are battling a throughput issue with an ISP at one of our branch locations. We are using a Cisco Meraki MX64 as our router which uses Auto-Provisioning IPsec VPN tunnels to connect to our head end Meraki unit in our Data Center. Upon first installation we noticed that throughput through our Meraki VPN to our Data Center was painfully slow. We were (and still are) seeing a max speed of 3Mbps (both up/down) for any type of traffic going through our Meraki tunnel. At first we thought the slowness was a Meraki issue since onsite speed tests to the ISP test server did indeed show near the promised 100Mbps up/down. We then opened a ticket with Meraki which eventually led to them sending us a brand new MX64 appliance. After replacement there was no improvement and we were still seeing the exact same slow throughput. The combination of that and knowing that we have other branch sites that use the exact same Meraki equipment and same exact VPN configuration back to the same Data Center/internet egress made us start to investigate the ISP connection as the issue. Our other branch sites are using other various ISPs with different speed offerings and iPerf results are showing the advertised speed through those tunnels (to our same public iPerf server).

Any assistance is greatly appreciated!
