Das hat Mainsoft geschafft. Über die Portierung spricht sich der Hersteller des Cross-Compilers unter http://www.mainsoft.com/solutions/pdfs/PerformanceStudy.pdf aus. Interessant finde ich die Performace-Ergebnisse: Die Anwendung läuft unter dem WebSphere AppServer genauso schnell wie unter der MS .NET Plattform.
The software vendor successfully ported their .NET based application platform onto Java EE using Mainsoft’s technology and professional services saving $1M in R&D costs. The performance of this application was tested on the same hardware and under the same stress test conditions. The ported version of the application showed equivalent performance in average response time, and equivalent performance in server throughput. Thus, an SLA could be met using the ported version of the application without additional hardware investment. The Java EE version of the application also showed that in multi-CPU environments, the scalability characteristics of Java EE and WebSphere Application Server began to show marked improvements over the original .NET application.
