   The average ping response across the internet is 34 ms, while the average   
   ping time within the VPN is 37 ms.  Not too much difference there.   
      
   At one location, download speed is 4900 kbps, and upload is 660 kbps.   
   At the other location, download speed is 1300 kbps, and upload is 770 kbps.   
      
   I just ran file transfer tests through the VPN, and got about 700 kbps,   
   so I guess the upload speed is the big culprit, not the VPN performance.   
      
   Bummer. I was hoping for a one-time cost to improve performance, instead of   
   paying for a higher class of service.   
      
   Thanks,   
   Ed
