EPDM Item performance question

We are implementing the use of EPDM Items to link all our sales and marketing documents, engineering data and mfg data to the EPDM Item. The Item will be our linchpin in our automation efforts.

I was wondering if it was advisable to turn on the "Enable Auto Update" on the linked files? Documentation says that this will keep the linked files at the latest versions. I was curious if this could be a performance killer if we have standard documents linked to 1,000s of items (i.e. a standard product pdf file that is linked to 750 different product family part numbers) and a change is made to the standard document. Anyone out there using Items in this way?
