Researchers evaluated the performance of the Intel PRO/10GbE LR Server
Adapter in three LAN environments: a direct single flow between two
PCs connected back-to-back via a crossover cable; an indirect single
flow between two PCs through a switch; and multiple flows through a
switch.

7 Gbps throughput and 12-microsecond latency.
<br>
sustaining end-to-end
TCP/IP throughput of 2.38 Gbps across a distance
of 10,037 kilometers (approx. 6,236 miles) between
Sunnyvale, California, and Geneva, Switzerland,.
