Crystal Reports Bundeled With Visual Studio 2008

Question

We are currently using the version of Crystal Reports that comes with Visual Studio 2008.  Many reports have 5-10 sub reports.
We are running a ASP.NET application and this application passes to the reports a XSD File as the data source. It can take up to 5 minutes sometimes for a report to process.
A couple of questions.
1. Is there a concurrent user limit (I have read 3 or 5)
2. Do the reports get queued up if more than 3 users are running a report?
3. If we have sub reports does each report count as a "user" for example if we have one user on the machine and they run the report that has 10 sub reports, would that be hitting a user limit?
3. Would upgrading to the 2008 version help us at all?
Any other recommendations?
Thank in advance!

Answer 1

1. Is there a concurrent user limit (I have read 3 or 5)
concurrent user limit is 3
2. Do the reports get queued up if more than 3 users are running a report?
+ Yes. If you go to the Event viewer, you should be bale to see messages along the lines of; license not found, waiting x seconds+
3. If we have sub reports does each report count as a "user" for example if we have one user on the machine and they run the report that has 10 sub reports, would that be hitting a user limit?
+ There are two distinct counts. Users, and print jobs. The print engine, can process 3 concurrent users. A print job, consists not only of the report, but also it's subreports. A page through is a print job. A search through the report is a print job. Print job limit is set in the registry and by default it is set to 70. The upshot of this is; if you have one report and one subreport in the detail section and the detail section has 100 records, you will run 1001 print jobs.
4. Would upgrading to the 2008 version help us at all?
Probably not. The same structure exists in CR 2008. Now, you say that you pass an XSD file to the report. Are you actually passing and XSD or a Dataset?_
Finally, remember that if you have 10 subreport in a report, you are running 11 print jobs right there. If one or more of those subreports are in the detail section, the number of print jobs increases accordingly.
