Re: RPi 3B+ gigabit ethernet bad download speeds.

A lot but that much better. Testing iperf3 from my bigPC to my Rpi3B+ I receive at 220 Mbps and 0 Retr. Of 10 consecutive tests the results are: 0,20,0,0,0,0,0,0,0,16 Retr.

Re: RPi 3B+ gigabit ethernet bad download speeds.

QoS != Flow control. Have you found any options to turn flow control on or off on your router? With it turned on I would expect very few retries. I have uninstalled luci-app-qos and qos-scripts on my TP-Link router and installed and configured luci-app-sqm and sqm-scripts . See pictures below. The ...

Re: RPi 3B+ gigabit ethernet bad download speeds.

@ jamesh The main conclusion we have come to - if your switch does NOT have flow control turned on, you will suffer a large drop in performance. This is due to the Pi being unable to service incoming data at gig speeds, and therefor a lot of retries are required for dropped frames. Now, desktop swit...

Re: RPi 3B+ gigabit ethernet bad download speeds.

ejolson dixit... While 200 Mbit download may seem fine at first glance, these tests were performed using a low latency local area network. The retransmits have a much greater impact when transferring data across a high-latency connection to the internet. Exactly. All this is a consequence of the us...

Test people:

Code: Select all

iperf3 -c bouygues.iperf.fr -p 5209 -R
This server works very well.

What I have seen is that the number of drop outs went from 5 or 6 per 1.5GB transfer down to zero. So I am expecting the link to be more robust, but not faster. When we have tested for speed ...
