I have set up a new SoftEther VPN-server, and ran into quite a bit of issues in regards of performance.
Currently, I now have one single hub on the server with a very basic setup. On the server itself, the speeds towards internet is great (500/500+ Mbps). This is set up on a dedicated 500/500 fiber connection in my office. Server is a quite new Xeon 8-core workstation running Ubuntu 18.04LTS.
But through the VPN, I get 0,1 to 4 Mbps downstream, while upstream is 300 mbps+. Connecting to a different server in the office on a another 500 Bps connection, gives me much better performance (this running on an old PC with Ubuntu 16.04LTS and an older SoftEther VPN-version).
As a client, I tried both my Windows PC with the SoftEther VPN Client and a Raspberry Pi2 running SoftEther VPN with cascade-connection to the server and a bridge to a secondary Eth-interface. Performance issue is present on both clients. Also here at home I have a 500/500 Mbps fiber-connection.
If a join a 15 Mbps multicast over the VPN, there is no issue - Multicast is UDP and on Layer 2.
Post your questions about SoftEther VPN software here. Please answer questions if you can afford.

Get it resolved. Installed Ubuntu 16.04LTS instead of 18.04LTS. Not sure if that alone was the reason why it now seems to work. I have a little bit difference in the ip-configuration too (two of the interfaces that earlier was dhcp is not using a static IP).
