you have reduced the amount of data transferred between the PHP level 
and the Javascript level, by sending less data in the querydata div.

Can you also reduce what is transferred between the MySQL server and the 
web server, by avoiding to generate "SELECT *" in the query generation 
part, instead selecting only the needed columns?
