Performance Degradation Through VPN

I suspect that the biggest reason your dial-up VPN downloads are so much slower
than your dial-up non-VPN downloads is that encrypted traffic doesn't compress
well (in fact compression is frequently counter-productive with encrypted
data).  Try turning off compression in your modems and see if the numbers are
closer.  You could also try downloading an encrypted file across the non-VPN
connection and see if goes slower.  My guess is that it will.
