I had a quick look at this. It appears the DartVM is now beating the JVM even at 100,000 iterations (Previously Java edged out Dart at higher iterations).

100,000 iterations takes ~45 seconds to run on my computer.

At a lower number of iterations the DartVM beats the JVM by a significant margin.

The benchmark is easy to run (On linux, maybe macos too). Just check it out, make sure dart, java and gcc are in your path, and execute run.sh.

Note, this code doesn't use the benchmark harness because I wanted to include the warm up time in the measurements. At a high number of iterations this doesn't make much difference.
