At work we have a Windows 2008 Server-based network with over 60 computers. We are planning to set up a Windows 2008 VPN server shortly to provide remote access, and I am wondering what kind of performance loss should we be expecting.
The internal network is 1Gbps and the uplink to the Internet is a 100Mbps line, so our users are used to a high-performance network. Browsing shared folders and opening large files within the internal network is often instantaneous. I am aware that we won't be able to obtain this kind of bandwidth through the VPN, and that, in any case, the VPN user experience will depend largely on what's on their side and, especially, between them and our VPN server.
Still, I would value answers to two particular questions:
- What kind of performance loss should we expect?
- How can we mitigate the performance loss? Is the VPN server hardware really important?
