I've installed SoftEther VPN Server on Ubuntu 16.0.4.1
VPN clients: iPhone, Windows 8 and another Ubuntu Server
Network Traffic Speed Test Tool:
without VPN:
- Download – 36.88 Mbps
- Upload – 4.93 Mbps
with VPN (L2TP or SSTP or SoftEteher VPN client with Local Bridge or SecureNAT):
- Download – 300.53 Kbps
- Upload – 4.79 Mbps
from VPN server to another server without VPN (same LAN, 1Gbps):
- Download – 0.95 Gbps
- Upload – 0.92 Gbps
from another server to VPN server via VPN:
- Download – 9.14 Mbps
-
Upload – 905.33 Mbps
-
Download -only – 88.18 Mbps
- Upload -only – 0.91 Gbps
Why Download is very low ?
