Transmission rate slows down when using mlvpn0

[beyondhong]

Hi, @zehome I have two 4G modules and I test their transmission rate via www.speedtest.net. Both of them can reach about 26Mbps. So theoretically I will get about 2X26Mbps if I use mlvpn.

I did some tests and I got these results:

1. one 4G module without mlvpn -> 26Mbps
2. one 4G module with mlvpn -> 14.17Mbps
3. on server side, 75Mbps
4. two 4G modules with mlvpn -> 10.8Mbps (tcpdump shows both two links carry data)

So it seems the transmission rate will slow down when using mlvpn0 and link aggregation did not take effect.

Here are my config:

// client ==================================== [general] statuscommand = "/tmp/root/c_mlvpn0_updown.sh" tuntap = "tun" mode = "client" interface_name = "mlvpn0" timeout = 30 password = "123"

reorder_buffer_size = 0 //disable reorder system by this way?

loss_tolerence = 60

[wwan0] bindhost = "wwan0" // get ip by interface remotehost = "120.42.xx.xx" //my server IP remoteport = 1600

[usb0] bindhost = "usb0" remotehost = "120.42.xx.xx" remoteport = 1601

Is there anything wrong with my config? Or what problem it might be? Thanks!

me too. MLVPN shows aggregated bandwidth as 50% of the slowest 4G link. I have two 4G modems. MPTCP kernel works much better with about 70% of sum of bandwdith of underlying links.
