What sort of issues would I face running large numbers (hundreds, perhaps thousands) of openvpn networks on one machine?

If, for example, one server wanted to create a separate VPN for every user on the system, that included all of their servers. There would be no internet routing, just separate VPNs between (user A and the server), and (user B and the server) etc.

  1. VPN software is using CPU. Most modern server CPUs have hardware acceleration units for encryption operations. The load should be similar with SSL. In the past encryption was slow. Nowdays it is not that slow compared with other operations.
