You probably remember Greg Leake first version of the .NET StockTrader sample application that he released nearly two years ago.  The goal was to help customers tune performance of .NET applications. Greg recently updated his evidence to compare cost performance on Windows vs. Power6, both with Websphere and the.NET Framework – read on!
Let’s start with costs… Greg’s findings demonstrate that customers can save up to 81% in total system costs by running applications on Microsoft .NET and Windows Server 2008 over IBM WebSphere 7 on Power6/AIX. The study also showed that customers who run their IBM WebSphere 7 applications on Windows Server 2008 and Hewlett Packard/Intel 64-bit blade servers can save up to 66% in total system costs when compared to running the same applications on IBM WebSphere 7 on an IBM Power6/AIX platform.  These results illuminate significant savings for businesses of all sizes, and particularly speak to the value of the Windows Server platform.  Our hope is that people are able to make use of these findings to get more for their money, either by making new investments or by maximizing assets they are already using.  Who knew WebSphere and Windows Server were such a match?  
Most folks tend to buy into the potential for cost savings but tend to speculate that they give up performance to get it.  The study found that the Microsoft .NET Framework on Windows Server 2008 handles 57% more load than WebSphere 7 running on IBM Power6/AIX, and IBM WebSphere 7 on Windows Server 2008 handles 37% more load than IBM WebSphere 7 running on Power6. So, what do these findings mean…two things:
1) Windows Server and the .NET Framework continue to be a powerful, leading combination for application development, deployment and management.
2) Customers who have made a bet on WebSphere can improve performance and reduce costs by running WebSphere on Windows.
