Using Firefox plugin Firebug, Loading the page first time, takes about 30secs, to load the page first time. Afterwards, all calls are made using AJAX, which takes 25secs to transfer data, based on the size of rows returned.
This time includes, the 9.6 secs taken by the script to execute, time taken by firefox to fetch data and then render it.
