Sure, take all benchmarks with a grain of salt. However it's worth noting that deltablue has been used to benchmark polymorphism in Smalltalk, Self, the JVM, and V8. Some of Nickolay's numbers are from a version of the code written at Sun labs, presumably for the very purpose of benchmarking the JVM. I think it's safe to conclude that in many cases the DartVM already performs similarly to the JVM, albeit with a much better start up time. Charles Nutter has some interesting follow up comments here: http://blog.headius.com/2013/05/on-languages-vms-optimization-and-way.html http://blog.headius.com/2013/05/on-languages-vms-optimizatio... Basically concluding that it's not static typing that matters, but predictable types.
