Is it accurate ?
a simple calculation :

One 1500 byte packet: 64 bits preamble + 14*8 bits Ethernet header + 1500*8 bits payload + 32 bits FCS + 96 bits interframe gap = 12304 bits
10Gbit/s = 10000000000bits/s 10000000000bits/s / 12304bits/pkt = 812743 pkt/s Data bits might not translate one-to-one into bits on the media so the actual packet rate might be slightly smaller.
