Hello all.
we interesting where from ns developers takes.
for example:
exalink fusion
110 nanoseconds port to port latency with full layer 2 switching. The
industry's lowest latency cut-through layer 2 switch. Supports ultra-low
latency multicast and broadcast.
Latency
Measured front panel port to port:
➔ 5 ns (Layer 1 tap/patch)
➔ 95 ns (Layer 2 aggregation)
➔ 110ns (Layer 2 switching) ( !!!we interesting in this parameter )
mellanox sx1012
Lowest Latency
• 220nsec for 40/56GbE
• 250nsec for 10GbE
• Cut-through latency between ports in different speeds
but cisco got different numbers, by packet size.

so what are real tests for this NS?
how to make REAL compare.
