FP math doesn't seem to be optimized in many scripting languages either. I suspect most people who are interested in scripting languages are acknowledging some amount of performance bleed. For those that are interested, there is an article that benchmarks numerical computing performance of the CLR using C# at http://msdn.microsoft.com/msdnmag/issues/04/03/ScientificC/=20 The performance isn't ideal but I suspect it is better than most scripting languages and should continue to improve. SciMark scores for various Java implementations: http://math.nist.gov/cgi-bin/ScimarkSummary Another paper talking about HPC and .NET & Java. http://www.sc-conference.org/sc2003/paperpdfs/pap251.pdf On the subject of JIT vs static-native, there is a paper on Marmot at http://research.microsoft.com/act/marmot.pdf. One could suspect these techniques could be applied to .NET=20 languages as well. It would be nice if there were more effective benchmarks for C# performance in the games domain but I am not sure what those would be.
