We have a desktop application using Telerik Reporting Q2 2009 SP1. We generate a PDF report and write it to disk. This process usually takes between 5 - 15 seconds depending on the report being generated (there are a number). We have 1 customer though who is running our application on Windows XP Pro SP3 and when they try to generate a report it takes up to 30mins!!! During this time 1 cpu of their Core 2 Duo 2.0GHz processor (4GB RAM) is maxed out to 100%. The report will eventually successfully generate and be written to disk, but it's just very strange behaviour.
The particular report in question has a cover page, 2 sub-reports, a bar graph with 5 bars, and a small number of text bound fields. We are using the NeedDataSource to dynamically hook up the datasource for the report. The time it takes for this method to run under normal conditions is approx. 4-6secs. This is still the same on the customers computer too. It is the Report Rendering after databinding that takes the remainder of the time.
We have not had any other customers report this behaviour and I am unable to replicate it for testing/debugging purposes. Is there any way I can turn on verbose logging in the telerik engine via a setting in the App.config file that will write a log file somewhere that might show what is happening during the report generation? We are running on .Net v2.0 (no 3.0 or 3.5 stuff at all).
