ASP.NET AJAX application extremely slow over VPN

I have a ASP.NET AJAX intranet application that has been running for a few months. It runs reasonably fast on the LAN.

However when going over a VPN it slows down dramatically. Even taking line speed into account its takes like 60 seconds to change a page. I eventually got a vmware up and running to test the VPN speed, so the connection is super fast, but it still takes the same amount of time. I can even remote desktop over the VPN to the VMware and its perfect.

This makes me think that its has nothing to do with line speed. FYI I am using Hamachi.

I have tried other VPN software and it gives the same results.

I am really stuck... any help would be much appreciated!

A: 

Try to add system counters for "Byte per second" and other similar parameters of you network. This helps you to figure out the bottleneck of you system.

Not sure how I can use this to pinpoint the problem with the ASP.NET code? I am fairly sure that there is no problem with the network. I can run other asp.net applications without any problems.

I found the problem was due to trying to do a dns lookup in the code. Changed to just the IP and now working!!!
