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.
