slow speeds from new york to shanghai

We are getting poor performance with a VPN from our main site in New York to a branch in Shanghai. We have a 50Mbps link in New York and a 30 Mbps link in Shanghai. however we only get about 500kbps. Is there anyway that we can improve this short of getting a guaranteed link between the two offices?

That was one of the things that i was thinging about. I know that the MTU is set to 1500. I will try reducing it and see what I get as a result.

We get 30 over 30 dedicated at the lesser site. When we test it to a local location we usually get about 80% of what it is rated at for upload. Even if it was 50% we should still be getting better speeds.

The VPN is between to Cisco ASA's, so should the MTU be changed on the inside or outside interface?
The MTU that will affect the VPN is on the inside interface.   ... Thinkpads_User
