If you look at it from my point of view there's a bug in armbian. At the very least it's now been reported even if I'm not clever enough to figure it out. You aren't showing much sympathy to the regular users trying to help out by such condescending language.

Of placing the device back with a new kernel/distro or even doing testing on it. I don't travel much and my friends who do don't have any experience nor equipment to change things.

Hi and thanks for the reply I have the device running official armbian at my location (already brought it back) and so I'm trying to figure out a way to "simulate" high latency. Any ideas? Otherwise we'll have to wait a few months so I can place it at it's intended location again. As you can imagine, this is something that's taken a LONG time. Many many months and progress is slow.

Hey fellas I have FOUR different armbian devices (one official armbian, three running ophub's armbian) which all seem to struggle with network throughput at high latency connections. It is not a cpu issue and this doesn't occur on x86 debian. Here's the odd thing. If I connect an ethernet usb dongle, like rtl8152b I get the full throughput even at high latency. What??? So it's a nic issue? I thought maybe the onboard ethernet isn't well supported by the kernel so I got a nanopi neo4 with onboard realtek gigabit running official armbian 6.12.3x ... AND it's slow too. Any onboard nic with armbian is slow in my tests. With slow I mean that a single connection gets 5-10Mbit. With a dongle I can get up to 100Mbit on a SINGLE connection from the same device. Why is a usb realtek dongle better supported than onboard realtek gigabit? I don't get it. Does anybody have an idea I could try? What's really difficult is that the problem only shows up at high latency. If I set up a new device at home (low latency) I get full throughput, but when it's in another country 200-300ms latency it just slows down to 5-10Mbit. The workaround with a dongle was just a fluke accident that I happen to notice. I truly believe armbian has a bright future but right now I'm tempted to go back to x86 for my needs and I'd rather not because arm SHOULD be better than x86 for IoT (my use case). Thanks for helping me figure it out. Love your work!
