title: Evaluate Performance of JSON.Stringify Function?
body: <p>I have a Extjs form which has around 50 fields to search. I am posting form  data in JSON format to server. Before sending the data I am appying JSON.stringify method to convert the JavaScript object notation data into JSON form. but it seems after applying the function, the search operation has become slow. Is JSON.Stringify method costlier ? I want to know more details about the performance of the method, Please suggest alternatives for better performance. </p>
