Hi
the biggest killer of network performance is latency - the delay in transmission of packets. This is normally a factor of the link to your ISP.
If you ping a machine on your LAN from the VPN client, how long does it take for the packet to get back? This plays a great part in throughput, since packets often need to be acknowledged by the other end before subsequent packets are sent.
We often find that WinGate VPN works best in conjunction with remote desktop or terminal services - providing secure access and connection for the remote desktop communications, and also the ability to transfer files etc, but network-intensive operations are best done locally on the remote desktop. It comes down to how the applications you run use the network. Some applications are designed really for local networks only (e.g. those that do intensive disk access or network transactions), and perform poorly when used over a link with high latency.
