Windows 7 64-bit clients with high latency

[Ivo Smits]

  I've experienced the same problem with a potential customer of mine.

Interestingly, the problem here affected both tinc and openvpn, which 
suggests that it might be a problem outside of tinc, possibly the tap 
driver?

PING response times for the public IP address were a lot better, never 
over 100ms. Tinc was used in switch mode.
