Site A SA540 : 50M/50M DSL (Country A) (15 users)

Site B SA540 : 2M/520KB ADSL (Country B) (10 users)

MTU: 1464 (Test on ping frame)

We has custom application server and work on  services port 80, this is old application and need to call up dos prompt java.

We make server on Site A and alos setup up port forward from WAN to custome application server.

I find out at Site B direct use http services over the WAN just need around 5-10 seconds to launch the applaciton

On the same machine, we use site to site VPN to connection the application, that will need around 15 ~ 20 seconds or more, alos sometime can not load success the application through VPN, how can I improve it? Or any suggestion I need to pay attend?

Thanks

Hi Chammy, your vpn is only as good as the slowest link. If you'd like better performance, upgrade the connection of the other end.

Chammy,

I'll echo Tom's comment.  One thing to keep in consideration is that buidling up the VPN tunnel adds overhead to the traffic flow so a slower response over a VPN compared to open access is to be expected and will be more noticable on slower links.
