Description Alex 2019-04-23 13:54:23 UTC 
I use Linux since 4.* kernel version and internet download speed always slower than on Windows 7/10. 
On Windows, speed about 90 mb/s.
On Linux, speed about 30 - 50 mb/s.

If download  via Torrent, speed is good: about 90 mb/s. But via other apps (all web browsers, skype and other) : speed about 30 - 50 mb/s. I tried a lot of Linux dists (ubuntu 14 to 18, KDE neon, Mint, Deepin and other). The bug is same.

Fix it finally!

Reason could be anything. And the info is quite vague. Please check whether there's any previous kernel version not showing this issue and what's the first kernel version with the issue.
And it would be helpful to know whether there's any trace of the issue in logs, e.g. syslog, network statistics (e.g. missed RX packets), etc.
And it would be good to see some iperf results.

How can I check it !? (kernel version not showing this issue and what's the first kernel version with the issue.)
Comment 3 Heiner Kallweit 2019-04-24 05:07:47 UTC 
Either your distribution provides also older kernel versions, or build and test all kernel versions available on kernel.org. And you could also check performance with another network adapter.

The OP is non-responsive. Closing.
