Hello.
Here is a simple network:
Powerful OpenVPN server connect to internet via 100mbit link in datacenter.
Powerful gate in office (Server) connects to internet via 80mbit link via PPPoE ISP connection.
One office PC (OpenVPN client) connects to datacenter via VPN, speed results (transfer files from client to OpenVPN server via Samba):
OpenVPN TCP: ud
5mbit, down 13mbit
OpenVPN UDP: up 64mbit, down 12mbit
PPTP: up 64mbit, down 39mbit
L2TP: up 52mbit, down 48mbit
How can I increase OpenVPN speed?
