STAC Report: Aleri/Solaris on 6-core Intel Dunnington

Solution based on Dunnington processors handles 67% more throughput than same solution using Tigerton processors Two weeks ago, STAC released a STAC Report on order book consolidation using the Aleri Streaming Platform running on a single quad-socket server using Solaris 10 and the Intel Xeon 7350 (Tigerton) processor (click here for that report). This server handled 180,000 order book updates per second with a mean latency of approximately 1.5 milliseconds and 99th percentile latency of approximately 3 milliseconds. On September 15, 2008, Intel released the Xeon 7400 series of 6-core processors, codenamed "Dunnington." Intel therefore asked STAC to re-run the exact same Aleri configuration after upgrading the processors in the server. Aside from the BIOS, nothing else changed about the system configuration, except that Aleri configured their software to use more threads in order to leverage the 8 additional cores in this box. The key results were: - Using Intel Xeon X7460 (Dunnington) processors, the Aleri/Solaris solution achieved 67% more throughput (300Kups) than the same solution using Intel Xeon 7350 (Tigerton) processors (180Kups). At this rate, mean latency was approximately 1.6 milliseconds, and 99th percentile latency was approximately 3.2 milliseconds. - The Dunnington-based system achieved 55% higher throughput than the Tigerton-based system for a given threshold of mean and 99th percentile latency. o Mean latency less than or equal to approximately 1.5 milliseconds at ingress rates of up to 280,000 order book updates per second. o 99th percentile latency not exceeding approximately 3.0 milliseconds at ingress rates of up to 280,000 order book updates per second (with the exception of one run at 20,000 updates/second).
