[Samba] smb service response times + OpenVPN

[Janos Dohanics]

Recently I had the chance to look at smb service response times over OpenVPN 
using Wireshark/TShark. Here are 2 samples. In both samples a Win XP Pro 
machine is connecting to a server running samba-3.3.7 and openvpn-2.0.6_9 on 
FreeBSD 7.2-STABLE.
