I have a VPN connection setup on a Notebook (Sony/Vista Biz). The VPN at host end (office) is configured on cisco 837. The problem is, applications on notebook are running extremely slow to the point that working remotely is highly ineffective. Is this common with VPN's? How can I improve VPN perfomance?

How can I make a VPN connection faster and more usable?

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
