TimeKeeper and Solarflare Achieve 300 Nanosecond Accuracy in Benchmarking for High Speed Trading

December 6th 2011 · 2 min read

FSMLabs® today announced that TimeKeeper™ time synchronization software and the Solarflare® SFN5322F Dual-Port 10GbE Precision Time Synchronization Server Adapter were benchmarked with time distribution accuracy as precise as 300 nanoseconds. Three separate, logged, multi-hour runs were performed by FSMLabs in response to a request by a high-frequency trading and hedge fund firm. The test was run using Precision Time Protocol in a plug-and-play mode with no special configuration.

“For high-frequency trading, a variance of a microsecond in time accuracy can be an operational risk issue that destroys competitive advantage,” said Cort Dougan, chief technology officer of FSMLabs. “The test with Solarflare was required by a highly competitive firm, and these results clearly support their trading strategies. TimeKeeper provides many additional benefits to trading operations, including fastest time delivery into application software, multi-time source management, and performance logging across the network. But time precision in the sub-microsecond range is the foundation requirement, and this is unquestionably available in this configuration.”

“Solarflare enables its customers to build the highest-performance, lowest-latency, and most scalable 10GbE networks in the industry. For aggressive trading firms using every technological advantage, our SFN5322F and its onboard Stratum 3 clock are best in class for data transport with high-precision synchronized clocking,” said Bruce Tolley, Solarflare’s vice president of solutions marketing. “We are pleased to have worked with FSMLabs to deliver this breakthrough solution for the distribution of high-precision time. We look forward to partnering together with common customers in the trading and financial services markets.”

Solarflare support is available now in TimeKeeper. For more information or a demonstration of TimeKeeper 5.0 with any hardware, network and software configuration, contact FSMLabs at
