Do we require a particular resizing of fusion instance when creating receipts through API in bulk?

Summary:

We have a requirement to create 100K receipts in fusion instance. Our approach is below:

1. We will use the REST API with batch action to create multiple receipts in fusion system. (preferred batch size - 500)
2. We will do application of receipts to invoices and other functional scenarios through StanardReceipt SOAP service in bulk.

Overall it will be ~100K receipts created through API services. Do we need any fusion resizing as we are bombarding with so many webservices calls in fusion so that we will not hinder the system performance and bulk creation process.
