EBS PO Integration - PO_OTM_OUT records processing very slowly

Hi...we have this situation come up every once in awhile where we get an influx of PO updates in the PO_OTM_OUT queue...like for instance a user closes a bunch of POs or Releases and about 200-500 entries get put into the queue and it just causes everything to back up...is there anything that can be ran or set to help speed things up? Right now it looks like they are processing about 1 record every 2-5 minutes and we are still waiting on updates from yesterday to catch up (So as of Friday 10:04 am....the last record processed was put in the queue Thursday night at 9:05 PM). We are down to about 40 records waiting to process, but we have users waiting for that information to get into OTM so they can hire out the trip.

EBS version - 12.1.3
OTM version - 6.3.1
Enterprise Manager 11g, not sure how to tell BPEL version

We have both Sales Orders and POs integrating to OTM

Thanks,
Janel
