How to Optimize PDF and PCL creation in C# using active reports3

I am working on Optimizing performace for one my batch process at work. This batch process reads data from couple of tables, Person --> employment Assemble the domain objects, create PDF and PCL files.
 Person
{
//person fields
List<IEmployment> EmploymentList
}
IEmployment
{
//employment fields
}
 I need to create a PCL and PDF file for each person. Currently I am looping through each peson, creating instance of ActiveReport setting person as data source to ActiveReport, Creating PCL, creating PDF and exit. I am loading 500 person records at a time, create pcl's and pdf's and read next 500 unprocessed person records. This is taking around 5 mins to complete 500 records, at times we might have 30,000 records to process which is equating to 5 hrs. I am trying to optimize if. Please let me know if there is a better way of generating this bulk pdf's and pcl's.
