LAN vs WAN

Hi,

We are using EAServer with JSPs in our application.The
problem is that one of the procedures (database procedure) used in the
application returns more than 2300 rows and at the backend i.e in the
query analyzer its execution time is about 40 secs but while running
the application in LAN environment it takes 10 mins or so But in the WAN environment the Internet Explorer gives a timeout error after 3 mins.
