Maximum throughput for 64 byte frame on RFC 2544 test

How would someone be able to perform an RFC 2544 layer 2 test w/ VLAN tagged & successfully pass 940 MBPS on a 64 byte frame? (Far side port that is being looped for RFC 2544 testing is 1 gig port)

This is what I’m referencing for maximum throughput calculations:

7 bytes of Preamble + 1 byte of Start Frame Delimiter + 12 bytes of Inter Packet Gap + 4 bytes VLAN = 24 Bytes overhead

Throughput = [Frame Size / (Frame Size + Overhead)] * Switch Port Capacity

[64 / (64+24)] * 1000 Mbps = 727 Mbps throughput for the 64 byte size frame.
