Poor Network Performance from VPN sites

[brwong6372]

We are experiencing poor network performance when connecting from hardware VPN sites. VPN sites have Cisco Hardware VPN client 3002 which terminates to Cisco 3005 VPN concentrator. Geting upload/download speeds of 355/484kbsp from VPN to surewest.com. If I remove the VPN and connect laptop directly to dsl modem, speeds are 3mb up and 1mb down. Any ideas what could be causing this?
