Solarflare Achieves Record Breaking STAC Benchmarks With Its OpenOnload Application Accelerator Middleware and Solarstorm SFN5122F SFP+ Dual-Port 10GbE Server Adapter

Company Conducts Joint Testing of Multi-Vendor Solution With Cisco and Informatica 29West

IRVINE, CA--(Marketwire - April 14, 2010) - Solarflare Communications, the pioneer in 10 Gigabit Ethernet (10GbE) solutions, today announced results of a multi-vendor test using Solarflare's OpenOnload Application Accelerator middleware, Solarflare 10GbE dual-port SFP+ SFN5122F server adapters, Cisco Nexus® 5010 Switch, Cisco® UCS C200 M1 Rack Server and Informatica 29West Latency Busters® Messaging (LBM). Solarflare's OpenOnload Application Accelerator contributed significantly to the difficult task of increasing the application-messaging rate while maintaining low latency and bounded jitter.

The vendors used the STAC-M2™ Benchmark to measure the messaging performance of the solution stack. STAC-M2 measures the ability of a solution to handle real time market data in a variety of configurations. The multi-vendor testing achieved mean latencies as low as 14 microseconds with very small standard deviations of the latency (or jitter) of just one microsecond. The highest throughput achieved was 2.1 million messages per second(1). The tests were audited by STAC® (The Securities Technology Analysis Center). The STAC Report™ is available at The solution stack for this report consisted of products available and shipping to financial firms today.

Jack Gidding, Associate Director at STAC, said, "Leading trading firms on the STAC Benchmark™ Council approved the STAC-M2 Benchmark specifications as the meaningful, transparent way for vendors to demonstrate the performance of a high-speed messaging stack. Achieving low latency or high throughput in these benchmarks is not easy. The test harness involves large market data messages, usage patterns ranging from black-box trading to enterprise distribution, and real-world challenges, such as slow consumers. We are pleased that Solarflare, Cisco and Informatica subjected their products to these tests."

For this STAC-M2 Benchmark, Solarflare's server adapters were installed in the servers along with Solarflare's OpenOnload. OpenOnload speeds up messaging and other types of applications, while reducing the processing work that the host server has to do. OpenOnload thereby simultaneously reduces the application's latency while increasing its performance, all while maintaining complete compatibility with standard TCP/IP and Ethernet protocols. In this testing, the participating vendors configured the multi-core Cisco UCS servers so that all interrupts and background processing tasks were run on a single core. OpenOnload was used to enable the application threads to run without contention with each other. This left all other cores in the Cisco UCS server completely free to run application code without any interruption, cross talk or congestion. This elegant division of labor among the cores achieved by OpenOnload contributed significantly to the very low latency and very low jitter of the total solution stack.

"High frequency trading customers are looking to use tested, benchmarked solutions that consist of best-in-class products. Over a period of several weeks, Solarflare worked closely and intensively with the technical teams from 29West, Cisco and STAC to complete the STAC M2 Benchmark testing. The results empirically prove the dramatic contribution of our OpenOnload Application Accelerator middleware with the SFN5122F server adapter to the low latency, bounded jitter and high message rates of the overall solution stack," said Bruce Tolley, VP Corporate & FinServ Vertical Marketing at Solarflare. "Standard 10 Gigabit Ethernet hardware will become the foundation of servers used in high frequency trading systems. OpenOnload dramatically increases performance without sacrificing the simplicity and application compatibility of TCP/IP and Ethernet."

"We were very impressed by the significant contribution Solarflare's SFN5122F 10GbE server adapter with OpenOnload provided to messaging application performance," said Greg Lorence, Product Manager at 29West, now a part of Informatica. "Our customers demand the lowest possible latencies from their systems. Messaging speed is a big part of that, but ultra-fast network-layer interconnects are another key place to gain a competitive latency advantage. The STAC testing proves that the combination of Cisco servers, Solarflare server adapters, OpenOnload and Informatica's 29West messaging can deliver really impressive results to our low-latency trading customers."

(1) Latency: Mean latency was 14 microseconds in each of the use cases where latency is a key end-user priority and messages are passed as opaque buffers, including STAC-M2.v1.0.BASELINE.LAT1, STAC-M2.v1.0.OVERLAP.LAT1, and STAC-M2.v1.0.DUALPROD.LAT1. Throughput: STAC-M2.v1.0.BASELINE.TPUT1 was 1.3 million messages per second. STAC-M2.v1.0.DUALPROD.TPUT1 was 2.1 million messages per second. Further details at
