Dissect the create accounting request

When the create accounting request runs, how much time is spent on updating the XLA tables, creating the actual journals, and compiling the report?  Our create accounting request takes about two hours to run.  We do not use the report that is generated because it is thousands of pages long.  We created our own version of the report that dumps into excel.  Is the report the largest part of the program?  Is there a way to exclude the creation of the report.
