Workbench vs ASP.Net MySQL database performance

Hi

I am using MySQL at the server end.

Web pages are developed using ASP.Net C#

When I try a query using my MySQL Query Analyzer, it takes only 1 sec.

Same query, if I execute through my Asp.Net web page, it takes nearly 20 seconds or more.

Why? What mistake I do?

Thanks
