PeopleSoft Integration to Oracle SES with Multi-Language setup

Hello PeopleSoft Community,

Would like to ask how have you setup your PeopleSoft Integration to Oracle SES for Multi-Language setup.  In our case, we have eight languages installed.  We have the following timing for our Indexation (Approx):

PTPORTALREGISTRY - All Languages - 2.5 hours - 78208 documents

EP_AP_VENDOR - Base Language - 5.5 hours - 229726 documents

EP_AM_ASSET - All Languages - 4.5 hours - 961608 documents

EP_GL_JOURNAL - Base Language - 18.5 hours - 1203355 documents

EP_AP_PAYMENTS - Base Language - 18.5 hours - 1818765 documents

Given that our EP_GL_JOURNAL and EP_AP_PAYMENTS runs for 18.5 hours for base language only, would like to ask what will be the strategy if we are going to run full indexation in production?  Is there a way to speed this one up of if the given timing is already the acceptable value, how can we deploy this, e.g. chunk the deploy and the like.  Would appreciate a respond.  Thank you.
