NetLogic Microsystemsから Low latency PHY (70ns, 既存の半分程度) が
発表されてました (Aristaの新スイッチに採用されたようです)：

"NetLogic Microsystems Announces Breakthrough Innovations to Achieve
 Dramatically Lower Latency for Next-Generation Data Centers"

"Andy Bechtolsheim, chairman and chief development officer of Arista,
 cited the technical leadership of, and close collaboration with,
 NetLogic Microsystems as key to enabling Arista to achieve the
 lowest Ethernet switch latency in the industry"

  "today announced breakthrough innovations in high-speed physical
   layer SerDes development that has resulted in the world’s lowest
   latency 10 Gigabit Ethernet (GbE) PHY solution for next-generation
   data centers."

.....
  "NetLogic Microsystems' new dual-channel AEL2020-LL PHY with
   integrated SerDes features an ultra low-latency of 70 nanoseconds
   (ns), which is nearly a half of existing solutions.  In addition
   to the ultra low-latency, the AEL2020-LL PHY device offers the
   industry's lowest power consumption and ..."

"Arista Advances Race to Zero with Sub 500 Nanosecond Latency Switch"
 March 15 2011
  http://www.aristanetworks.com/en/news/pressrelease/312-pr-20110314-01

  "today announced the Arista 7124SX, the fastest switch in the world
   with standard SFP+ interfaces. With sub-500 nanosecond latency, the
   Arista 7124SX is ideal for financial trading and ultra low latency
   applications as a leaf or access top-of-rack 10Gigabit Ethernet
   switch."

  "Arista also introduced Latency Analyzer (LANZ), a new software
   capability to monitor and analyze network performance, generate
   early warning of pending congestion events, and track sources of
   bottlenecks. In addition, a Solid State Disk (SSD) is available as
   a factory-option and can be used to store packet data captures,"

  ""The addition of the Arista 7124SX not only improves network latency
   dramatically by 20% (over 100 nanoseconds), but also represents a
   highly efficient and more compact design" stated Anshul Sadana,
   vice president of customer engineering at Arista Networks."
