udp2raw 20200818.0 带宽非对称网络速度异常 #452

发现一个现象，使用 udp2raw + wireguard， 家用2条宽带，一条下300M,上30M 另一条下500M，上50M， 上下行不对等。 使用udp2raw后，下行速度会降低到和上行一样的速度，而且抢占上行速度会影响隧道中的下行速度。CPU占用很低， 去掉udp2raw直接使用wireguard， 速度和宽带一样，上下行不对等。

--raw-mode faketcp --cipher-mode aes128cbc --auth-mode hmac_sha1 --lower-level 模式。 不清楚是不是bug。

it's weird, I am not sure the reason.

if you would like to further debug the issue, maybe you can try some other solutions and see if they have similiar problems, for example:

  1. openvpn with tcp mode
  2. phantun + wireguard.

other ideas: when the problem 下行速度会降低到和上行一样的速度 happens, you download a large file from VPS to your PC (without going through udp2raw/wireguard) with real TCP, see if real TCP can make use of the missing bandwith.
