Sounds like the intended efforts for DSA bringup for 21.x and beyond have been fruitful. :) On 2021-12-22 08:45, Kristian Evensen wrote: Hi, On Tue, Dec 21, 2021 at 6:34 PM Kristian Evensen wrote: Since the only change between my sets of tests is the software, something has clearly

I generalize, but this is a problem which affects a few devices in the DSA bring-up. Some platforms require some tinkering and tweaking, and perhaps input from the chip-set manufacturer (or information from a datasheet of the chip-set) if things are to improve. DSA brings advantages and is

Hello, I am currently performing some performance measurements, comparing the (wired) routing throughput (WAN <-> LAN) of 19.07, 21.02 and master on mt7621 (ZBT WG-3526). I have connected one client to my LAN and one to the WAN, and use iperf3 to measure. I create parallel flows (in order to take
