Solarflare and Arista Networks Announce Completion of Multi-Vendor Benchmarking of Market Data Solution Stack

Full Test Report Available in the STAC Vault

IRVINE, CA--(Marketwire - December 17, 2010) - Solarflare, the company pioneering 10 Gigabit Ethernet (10GbE), today announced the successful completion of a multi-vendor test using 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 very low mean latencies with very small standard deviations of the latency, also known as jitter. According to the policies of STAC, the specific results may not be disclosed publicly. A complete 89-page benchmark report has been made available to banks, trading firms and other end-user members of the STAC Benchmark Council with access to the STAC Vault™ (

The solution stack for this report used products available for shipping to financial firms today and consisted of the following components:

  • IBM® WebSphere® MQ Low Latency Messaging v2.4.0.2
  • Red Hat Enterprise Linux Server AS 5.5
  • Intel Xeon CPU E5530 @ 2.40GHz
  • IBM® x3550 M2 Model 7946-E2U
  • Solarflare SFN5122F 10GbE adapter with OpenOnload
  • Arista Networks 7124S 10GbE switch

The report illustrates the very low standard deviation of latency (jitter) that was observed during testing. The elements of the solution stack and their configuration contributed to the low jitter. This included tuning the server systems so that all interrupts and background processing tasks were run on a single dedicated CPU core.

The Solarflare SFN5122F is a low-latency, low-power 10GbE server adapter. For the STAC-M2 test, Solarflare's OpenOnload application acceleration middleware was used in combination with the SFN5122F to enable full operating system bypass, which dramatically reduces host processing overheads and enables high transaction rates, while substantially reducing application latency with very low jitter. Solarflare's OpenOnload library was configured to enable the application threads to run without contention with each other, and without requiring any interrupt processing or other interaction with the kernel active on the dedicated core. These techniques implemented in Solarflare's OpenOnload enabled the system to be entirely vertically separated on CPU cores, avoiding any application level crosstalk.

The ultra-low latency, cut-through switching functionality of the Arista 7124S switch and its dynamic allocation of packet memory are major contributors to the benchmark results. The Arista 7124S also features a fully non-blocking architecture from any port to any port, in L2 or L3 mode and for all packet sizes at GbE or 10GbE speeds. This fully non-blocking architecture ensures that the switch is never the bottleneck in throughput tests.

The STAC-M2 Benchmark specification tests the ability of solutions, such as messaging middleware, to handle real-time market data in a variety of configurations. According to STAC, the specification reflects the input of seven leading trading firms and six vendors of high-performance messaging. STAC-M2 Benchmark provides key performance metrics, including throughput, latency, power efficiency and CPU/memory consumption. The tests provide key performance metrics under several scenarios, such as undisturbed flow and exception conditions like slow consumers. The STAC-M2 benchmark can be used to provide a "level playing field" for comparing any messaging configurations.
