29West's Latency Busters Messaging Software Selected for National Stock Exchange's New Technology Platform

29West, Inc., a leading provider of high-performance messaging software solutions, and National Stock Exchange (NSXSM), the nation's first all-electronic stock exchange, today announced that NSX has based its market data distribution system for its newly launched technology platform, NSX BLADESM, on the 29West Latency Busters Messaging (LBM) software.

Warrenville, IL, and Chicago IL (PRWEB) November 27, 2006 -- 29West, Inc., a leading provider of high-performance messaging software solutions, and National Stock Exchange (NSXSM), the nation's first all-electronic stock exchange, today announced that NSX has based its market data distribution system for its newly launched technology platform, NSX BLADESM, on the 29West Latency Busters Messaging (LBM) software.

LBM has set a new performance standard in high speed messaging since its commercial release in November 2004. After extensive testing against other commercially available messaging solutions, NSX chose LBM because of the stability and performance advantages it provides.

"Launching an entirely new, state-of-the-art technology platform, our goal was to offer the lowest latency and greatest fairness in data delivery and stability in the face of growing volume." said Paul Arber, NSX Chief Technology Officer. "LBM provided us a superior performance advantage. With the vast majority of exchanges today running legacy messaging solutions, we see LBM as one of the best design decisions we have made to help us deliver the very best service to our customers." he added.

"We are very pleased to be working with the National Stock Exchange and to be a part of this industry leading solution." said Mark Mahowald, President and Founder of 29West. "As latency and stability under load become more and more critical, we are seeing continued growth in the

market for LBM. The National Stock Exchange is part of the trend toward higher performance data delivery and that trend is forcing many firms to reconsider how they distribute and share data. This pressure towards low latency and high performance plays well for us since we offer the highest performing messaging software on the market today."

29West offers LBM as a stand-alone product for use by exchanges, performance-focused trading shops and large end-users that require high-performance messaging solutions. 29West also provides an OEM licensing model to allow financial market application vendors to embed LBM inside a broader market solution. 29West's strategy is to meet the needs of a growing array of sophisticated users who are looking for a market advantage in their data-delivery architecture and view lower latency and higher throughput as advantages they can leverage to improve their competitive position.

NSX launched NSX BLADE on October 23, 2006. Incorporating LBM, NSX's new technology platform was built from the ground up to meet today's speed, price and service needs. Designed by leading IT experts with proven success in this space, the new system was built with today's most advanced technology, rather than being based on a legacy system. The platform offers unprecedented speed, scalable capacity, connectivity options and highly competitive exchange pricing due to NSX's low overhead and unique operating leverage.
