Hi all,
I have a very strange congestion (i expect) problem.
When i transfert a file between client and server, i have a very high ping latency (>1000ms), packet loss, etc... No problem outside the tunnel.
When the transfert is done, the ping return to normal (<30ms).
I have tried to modify mtu, mssfix, fragment, switch from tap bridging to tun routing, etc.. but no way.
I have tried to modify txqueuelen parameter, and when i increase it, i get more latency (and packet loss), when i decrease it, it's better !
I made lot of test, and the best txqueuelen i found is 10 on client side. With this value, and when i upload (or download) a file to (or from) server, the latency is about 100ms to 200ms...
The operanting system (on server and client) is Linux (ArchLinux) and openvpn 2.2.2.
Do you have an idea ?
Thanks in advance.
