Robert A. Wlodarczyk points to the new TMC benchmarks of .NET vs. Java. The first benchmark showed that .NET was 2-3x faster that Java and this resulted in a lot of critisisms form the Java camp. TMC has now redone the whole thing with the involvement of the Java community etc. The report is avbl at the TMC Site.
This time Java has performed better and in some cases the performances are almost the same, while in others .NET still maintains the lead.
