I have to ckarify. The problem is NOT with receive/download speed, but with SEND. SEND speed on Ubuntu machine are too low. Iperf is a bit backwards, but I confirmed it by checking my windows pc traffic.
I installed the mainline kernel 4.19.2 and the problem didn't go away, so the problem hasn't been addressed. ** Description changed: - Testing with iperf3 receive speed is only 750mbps while transmit speed - is normal - 940mbps. + Testing with iperf3 send speed is only 750mbps while receive speed is + normal - 940mbps.
