I've searched the forums on this issue, haven't really found the answer.
I have several nifty little sales reports which crunch a ton of data quite efficiently and render in just a few seconds in Report Manager. I've pushed as much of the data processing back to the server as possible, use a stored procedure (with parameters) in a shared datasource, don't return unneccessary data, all that. It works great.
When I first developed the reports, I continued generating my charts (which use the same data as the reports, just grouped differently) in Excel and pasting them in as images. Now I want to stop that nonsense and use the SSRS charts. I fooled around with the charting function and got a reasonable facimile of my Excel charts, two per report, which use their own separate stored procedures and the same shared datasource.
Now, reports that used to render in 5-8 seconds may take 1-5 MINUTES. Help! It's definitely the charts--taking them back out fixes the problem.
I have complete control over the datasources--would it make more sense to use non-shared sources, or to create totally separate shared sources? I saw a post that recommended "making data calls non-synchronous," but I have no idea how to do that.
Thanks for any suggestions.
On further investigation, it appears that deleting EITHER ONE of the charts brings the rendering time down almost to the same time as no chart at all. It's apparent that having MULTIPLE charts on a page multiplies the rendering time exponentially (I'm gonna tell Edward Tufte!)
This happens whether I put the charts side-by-side (preferred) or one above the other on the page--they just take FOREVER to render.
Anybody...?
