    });
    }

For backend I using SQL server-05. When page is loading It getting more time to load, above functions takes 30+ seconds to load.

How to optimze function calling?..

You could aggregate all the queries into a new web method which will perform all the SQL queries at once. Then send a single AJAX request to this new method. And as far as your SQL server is concerned you could also send multiple SQL queries into a single round-trip. Try optimizing the SQL queries as much as possible. Also you could cache the results of some expensive queries.

As long as /some code is not too much there is not really much you can do. These ajax calls area light-weight. Your problem is probably in the backend, where you send your requests to.

To debug/profile your problem, first check your ajax requests. Check them in a web-tool like Firebug and see that your request is expected. There you can also check which of your requests takes how long.

As you now see your bottleneck (e.g. requesting Contents.asmx/GetTitles is what takes so long), check your server that provides that page. As you did not provide code of that one, we can not help you there. But that’s where you have to look for next.
