writes "Computerworld's Steven J. Vaughan-Nichols reports that the London Stock Exchange is abandoning its Microsoft Windows-based trading platform: "Anyone who was ever fool enough to believe that Microsoft software was good enough to be used for a mission-critical operation had their face slapped this September when the LSE's Windows-based TradElect system brought the market to a standstill for almost an entire day.... Sources at the LSE tell me to this day that the problem was with TradElect.... Sources...tell me that TradElect's failure was the final straw for [the ex-CEO's] tenure. The new CEO, Xavier Rolet, is reported to have immediately decided to put an end to TradElect. TradElect runs on HP ProLiant servers running, in turn, Windows Server 2003. The TradElect software itself is a custom blend of C# and .NET programs, which was created by Microsoft and Accenture, the global consulting firm. On the back-end, it relied on Microsoft SQL Server 2000. Its goal was to maintain sub-ten millisecond response times, real-time system speeds, for stock trades. It never, ever came close to achieving these performance goals.""
