Anyone using Jasper Reports or anything else?

Anyone out there using JasperReports with Coldfusion 8? cfdocument and cfReport have such a performance hit on our box when we try to run certain reports. IE - Report Cards We need something that would be able to run 100+ pages of dynamic data quickly and efficiently. If anyone has any suggestions of what we could look into or how to get Jasper up and running I would appreciate any help.

Thanks.
