[pptp-server] Performance difference between TCPIP and SMB traffic

[Tife Chan]

Yes, exactly what i'm thinking.
I peformed another test, under local network enviro6nment, SMB is about 3
times slower than FTP.
Back to the VPN, as both FTP and SMB traffic is encrypted, theoretically..
the max speed for SMB should be 3 times slower than usual TCP traffic.
Anything I'm missing?
