We have just set up SoftEther server on Windows Server 2012 R2 Std, and on another Windows Server 2012 R2 DC.
Tunnel runs great, we have set it up to allow 32 connections, and disabled encryption to ensure best possible throughput.
We run iPerf 3 in both ends to test bandwidth.
iPerf climbs to 178 Mbit/s, then drops to about 34 Mbit/s
Subsequential runs are only about 34 Mbit/s.
If we disconnect SoftEther and reconnect, then iPerf again runs about 170 Mbit/s and then drops to 30'ish.
Why is this happening, and how can we solve it?
Servers are not at high load, and normal internet speedtests show about 5-600 Mbit/s on both servers, connected with 1Gbit/s to the internet.

Could you try again the test with speed test tool in the SoftEther VPN?
