Report slow to generate

[Fuigi]

Hi,

I created a report with 10 graph. And 4 dropdown list (year, month, structure and indicator).

But when I change one of the value of a dropdown list the report take near to 1 minute to make the modification in the graph.

I use one query to populate every dropdown list (so 4 query)

And 4 other query to my graph, with all query have different filter.

I try two way, by query extract my data from my database.

And I try to create a package.

By these two way I have approximatly the same time to generate the report.

Do you know why the report take so much time ?
To much graph on the report ? To much query ?
