Minix U22 XJ Max internet speed issues

CoreELEC 19.4-Matrix_rc1 and addon Speedtest. Box connected via LAN.
When I check the internet speed, the upload speed is very different from the download and is significantly lower, although in Android is very similar. My internet line speed is 300 Mbps. Android shows about 260-280 Mbps downloads and about 180-230 uploads. In CoreELEC downloads is about 160-200 Mbps and uploadas just about 30 Mbps. At first I thought it was because CoreELEC was working from an SD card, but after installing it to the internal memory, the result remained the same.

I’m not sure if I’m writing on the right topic.

If you need a log, I’ll give it in the evening.

You need to test speed locally to get real numbers. This is from my box

Thank you @vpeter. I see that everything is great.
