DSpace 7 - Optimizing filter-media command line tool

[R W]

Hi Everyone,

We are in the process of migrating a larger DSpace instance from 6 to 7. While running the /opt/bin/dspace filter-media command line tool that generates thumbnails, we have noticed that it takes a significant amount of time to complete (a month and a half). 

In preparation for this instance's production migration, we were curious to know if anyone had experience optimizing this or similar command line tools. We are considering adding more java resources and would love to hear if community members have any suggestions. Thank you and take care.
