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. 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.
