Two years ago, the London Stock Exchange (LSE) with its TradElec Windows-based C# and .NET programs crashed and took out the Exchange for almost 7-hours. That’s an eternity in stock market terms. Months later, the LSE’s CEO was history, and the LSE announced that it was dumping TradElec. Last year, the LSE announced that it was going to move to Linux. Now, the LSE is just about ready to switch over to Linux. Not only does it work, the new Linux-powered LSE runs faster than any other stock exchange on the planet.
