I have simple web application which shows results of analysis in charts (chart control which comes with VS2010).
SQL queries responsible for fetching data used by charta usually finish in less than three seconds, but for page creation and opening it takes at least 60 seconds.
One chart is fast line and other is column. Both have three series (A,B and C=A+B).
I use SqlDataSources and on chart page there is virtually no code.
How can I improve performance?
