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?..

Answer 1

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.
