BEx Analyzer 3.1 Workbook Performance

Hi SAP Gurus,

I have to evaluate the performance of BEx Workbook in SAP BW 3.1. Some of the CCA Workbooks takes 1 hour to load. As I know RSRT can use to evaluate the query performance and RSTT is use for workbook trace in BI 7.0 but how can i evaluate the performance of BEx Workbook in SAP BW 3.1. All kind of help will be appreciated.

Thanks in Advance to All.
