Optimize XML Publisher in EBS R12

Dear All,
I hope this is the Appropriate Forum for posting with respect to above subject.
We have recently gone LIVE on the HRMS Suite R12.
Our Reports have been developed using Reports Developer with the Layout in XML Publisher.
There was a Report that we have run for Payroll for the Month of June which was working correctly.
Running the same report in July has for effect that it is taking a very long time to run and hangs.
Pls. advise if there are any optimizations that can be done to resolve this.
