Solarflare’s Solarstorm® vNIC with 29West’s LBM Achieves Sub-20-Microsecond, Infiniband-Like Latency over 10 Gigabit Ethernet

Solarflare Communications, the leader in standards-based 10 Gigabit Ethernet (10GbE) silicon, and 29West, Inc., the market leader in high-performance, low-latency messaging solutions, today announced results of a multi-vendor test at STAC. The report found that the Solarstorm vNIC, in conjunction with 29West’s Latency Busters® Messaging (LBM), achieves sub-20-microsecond, Infiniband-like latency over 10GbE in a one-way latency test, while sustaining target message rates up to 125,000 messages per second (msg/sec). This latency was also very deterministic with less than 6 microseconds of standard deviation (jitter). The testing, which used UDP multicast, accomplished message throughput up to 550,000 msg/sec and 4.51 Gigabit per second with a single sender.

STAC measured the performance of messaging middleware based on 29West’s LBM with Solarflare SFE4002 10 Gigabit NICs and a Cisco Catalyst 4900M 10 Gigabit switch. The test platform used servers and processors typically found in use by financial firms today. Read more about the report at

Jack Gidding, associate director at STAC said, “Using servers commonly deployed at securities firms, this Ethernet-based solution delivered low latency and low jitter in an unmodified middleware application. This is significant because improving performance without requiring costly application modifications is very attractive to today’s financial firms.”

Enabling financial trading customers to implement highly predictable systems, Solarflare’s 10GbE solutions provide a competitive advantage and offer increased overall speeds, more accurate trading and higher profits. Now, financial firms can use off-the-shelf Ethernet, TCP/IP, UDP and multicast solutions to accelerate market data systems without requiring the implementation of new wire protocols or changing applications. By leveraging the Solarstorm vNIC with OpenOnload™, IT managers are able to build market data delivery systems designed to handle increasing message rates, while reducing message latency and jitter between servers.

Application latency and throughput are crucial decision factors for financial firms when designing their market data trading networks. The STAC test results prove that a 10GbE infrastructure that includes Cisco's Catalyst 4900M is capable of delivering high message rates while consistently maintaining low-latency. The Cisco Catalyst 4900M is recognized in the industry as a best-in-class multicast switch with one of the lowest packet latencies on the market.

“In the electronic trading markets, firms can profit from as little as one microsecond of advantage over competitors. This drives organizations to find microsecond-level optimizations of the systems fueling their trades,” said Bruce Tolley, vice president of corporate marketing at Solarflare. “With our vNIC and OpenOnload technology, off-the-shelf 10GbE hardware can be used as the foundation of messaging systems for electronic trading with no need to re-write applications or use proprietary, specialized hardware.”

“We were very impressed by the significant contribution Solarflare’s Solarstorm vNIC with OpenOnload provided to application performance,” said Gregory Lorence, head of product management and marketing at 29West. “Based on the STAC testing, this is the lowest latency and highest throughput NIC we have ever seen.”
