What sort of VPN?
What sort of network connections?
What units? milliseconds?

Is their high latency outside the VPN? Or without the VPN?

A general solution would be to use a token bucket to slow it down, or reduce the queue length on the offending router.

a site-to-site vpn, with 2 3640 router, its already up, the only problem we are having 1000-2000ms when transferring any files, do you have any solution?

What does "ping" with big "packetsize" give you?

big packet size, makes transferiing really slow and annoying theres no sense of having a vpn if you cannot transfer files and haveing fast connection, and yes sir i've seen those links, but I need more specific asnwer like configs in routes and some vpn commands
