"Myricom DBL 2.0 Achieves Lowest UDP and TCP Latency for High Frequency
 May 2, 2011

  "... today announces DBL 2.0 software for its Myri-10G 10-Gigabit
   Ethernet network adapters. DBL is specifically designed to provide
   ultra-low latency communication, with rapid time to deployment, for
   high frequency trading (HFT) and other 10-Gigabit Ethernet
   latency-sensitive enterprise applications."

  "Myricom DBL 2.0 software has benchmarked application-to-application
   UDP latency of under 3.5 microseconds and transparent sockets TCP
   latency of 4.0 microseconds."
  "DBL leverages Myricom's extensive experience with kernel-bypass
   software techniques that allow user-level applications to
   communicate directly with network adapters, eliminating overhead
   and latency traditionally incurred by interactions with the
   operating system. Removing overhead allows data to move between
   applications and through the network in the least possible time."

  "DBL takes advantage of kernel-bypass firmware in Myri-10G NICs to
   allow high-priority user threads to send and receive IP frames

"Mellanox Message Acceleration Software Enables Lowest-Latency for
 a Wide Range of Financial Services and Web 2.0 Applications"
 May 16, 2011

  "Mellanox VMA 5.0 delivers sustainable latency under loads of over
   2.5 million packets per second and dramatically improves UDP latency
   to under 2.0 microseconds and transparent sockets TCP latency to
   under 2.5 microseconds, nearly two times better than competitive
  "VMA is a dynamically-linked user-space Linux library for
   accelerating messaging and streaming traffic. Applications that
   utilize standard BSD sockets use the library to offload network
   processing from a server’s CPU, with no application changes
   required. The application traffic is passed directly to the
   Mellanox ConnectX-2 10GigE or 40Gb/s InfiniBand adapter from the
   application user space, bypassing the kernel and IP stack and thus
   minimizing context switches, buffer copies and interruptions
   resulting in extremely low latency and higher throughput."
※こちらも Mellanox ConnectX-2専用でしょうね。

"Mellanox Sets New Low-Latency Record for Real-time Market Data over
 10GbE on IBM Systems"
 May 18, 2011

  "... today announced a new record in low-latency messaging
   performance for Ethernet networks based on the latest STAC-M2
   benchmark test conducted by Mellanox on IBM systems. The record was
   achieved using Mellanox ConnectX-2 EN 10GbE NICs with RDMA over
   Converged Ethernet (RoCE), the IBM BNT RackSwitch G8264 10GbE
   switch, and IBM x3550 servers running IBM's WebSphere MQ Low
   Latency Messaging (LLM) technology."

  "The Mellanox and IBM solution outperformed the most recent record
   holder (based on a comparable configuration), achieving a 30 percent
   improvement over results that were announced just two months ago."
