How do I improve the transfer speed of a RVS4000 VPN tunnel?

I have a VPN tunnel using 2 Linksys RVS4000 routers. I'm using the same ISP at both ends ( a cable provider with 512 Kbps upload speed and 7.5 Mbps download) . I have a Windows PCs at both ends. The transfer speeds are impossibly slow. When I transfer a 1 M file between 2 machines I get about 10 kbps transfer rates.

I need secure access to a 54M database and these speed make access impossible.

These are the settings of the tunnel

Keying Mode:      IKE with Preshared Key
Phase 1:
Encryption:        3DES
Authentication:       MD5
Group:        768-bit
Key Life Time:        86400 Sec.

Phase 2:
Encryption:        3DES
Authentication:        SHA-1
Perfect Forward Secrecy:       enable
Preshared Key:
Group:        768-bit
Key Life Time: 28800

At the time I tested this there would have been essentially no other upload traffic on either end.

I've tried moving both smaller files (images - <1MB) and larger files ( data files - 50 MB) with speed ranging from 2 - 17 kbps. These files were moved using using shared folders on Windows which I believe is SMB.

Using Speedtest.net I got 2.57 MB/s download 0.46 Mb/s upload and 105 ms ping.
