Hi all sorry for pasting wrong results.
Here you got correct one for UDP as I have not noticed that default
for UDP is only 1Mbit

Ok, this will most likely be latency causing your problem. Please
try a UDP test and see what you get.

Over the leased line I did some tests to servers in NL DC and
FR DC, also BT provided me with iperf server and it was same
result.

Ok
So from your house you can iperf to and from the servers at
1G over the microwave.
Where are you trying to iperf to and from over the internet line?

Hi Wojciech
I'm not sure I quite understand the topology.
Is the leased line an internet service or it a private
circuit between sites?

Hi Paul,
It is 2ms, but all test I am performing from server
directly connected to CCR1036.

What is latency difference between the microwaves
and the leased line?

Hi,
I've never used queue to rate-limit
download.Line has been upgraded both ways
because with 10 parallel downloads, I can max
out line to 960Mbit.

Paul Bone wrote on 28/05/2020 16:32:
Hi Wojciech,
That sounds suspiciously like the 500M to 1G
upgrade has only been configured in one
direction to me. I have seen this done many
times - some providers more frequently than
others.
The CCR will happily pass that traffic all
day, but does it have a queue configured to
rate-limit the download?

Hi Paul,
As a main router I am using Mikrotik
CCR1036-12G-4S, BGP with full tables, two
esxi servers connected to it directly and
few other servers, also company network
and few gigabit microwave links, one to my
home so I can work remotely
. Over the microwave links I can achieve
full speed for both upload and download
(inside my network) using iperf3. I can
also utilize full upload. But same with
download. To be honest I have 1Gb leased
line in different location from different
carrier and I do not have such problem
with bandwidth speed. I am really
surprised as I just did an upgrade from
500Mbit to 1Gb.

Wojciech

Hi,
Have you tried using UDP over TCP on iperf?
This could also be caused by the device
you are using unable to process the
speeds - have you tried a back to back
iperf test directly between two devices
before putting them over the leased line?

Hi all,
I have 1Gb lease line from BT Net and
I have an issue with download speed
for one thread download, I can't
achieve more than 500Mbit over it,
but upload with one thread is going
full speed. To do my test I am using
iperf3 also perfsonar with same
results. I have reported it as a
fault but they said if I want to
utilize full speed I have to use
multi thread download. I do not
believe that is right. What can I do
about it?
