Why are Out-Of-The-Box templates in RRDG using so much memory?
The RPE templates that are included in RRDG for DNG: Print Module Book, Print Module Table etc Are extremely slow when generating documents. Up to an hour in some cases. Also, the rrdg log(see warnings below) shows memory usage to be very high Short of increasing the JTS resources, is there any way to improve performance?

Are you using a 32bit JRE? The maximum heap size is way too small. Switch to a 64bit installation if that is the case.
The memory requirement really depends on the module that you try to print. If you try to print a module containing thousands of requirements, undoubtedly huge amount of memory is required to handle such load. |

Hi Donald, Thanks for the quick response. You are correct some of these modules have over a 1000 artifacts. Below are details about the VM and JRE(looks to be 64bit?) What do you recommend setting the heap size to?
VM Memory Usage
Maximum Memory Allocation 16384 MB
Application VM
1.6.0
Thanks,
Dan
