[pptp-server] Performance difference between TCPIP and SMB tr affic

[Jamin Collins]

I may be reading too much into this, but I'm getting the impression that
both of the tests are being perfromed through the PPTP connection.  Thus,
the encryption/decryption is happening for both the FTP and the SMB
transfers.  Thus his concern over why FTP is 10 times faster than SMB.
