[Stress/Load Testing] Native Infusionsoft Order Forms

Hello,

Has anyone ever experienced load issues with native infusionsoft order forms?

If we have 8000 concurrent users on an order form, of which 2500 are filling in the details and submitting the order, will Infusionsoft order form crash or be slow or not be affected?

Timeline: link shared to orderform 2 pm, peak traffic 2:10 pm, peak checkouts 2:16 pm and then it decays over time.
