Volume of Invoices in CRM Billing

Hi Guys

Do you have any idea about the volume of invoices which CRM can handle if we use CRM as billing?

In our current scenario we will be generating 1000Invoices per hour.So do you think ECC can handle this amount or CRM billing has the capability to handle or CRM billing should not choke with this amount of volume.

We are not using tax calculation in our system.
