Results, allowing enough iterations for the VM's to warm up.

Comments on other aspects of the benchmark:

The DartVM uses more memory than V8, and less than the JVM. Dart and V8 start
up faster than the JVM (Not much of a surprise there). However interestingly,
V8 appears to startup measurably faster than the DartVM. When testing a single
iteration, V8 consistently takes ~10ms to start the benchmark, and ~20ms to
execute it, versus Dart, which takes ~30ms to start, and also ~20 to execute.

Using a script snapshot had no measurable impact on start up time. This
probably reflects the small size of the benchmark, which doesn't use much, if
any (excluding List) of the standard library code.

At a wild guess, I'd say the start up time difference is due to Dart having a
larger standard library, thus a larger initial snapshot, which takes a little
longer to copy into memory. For usage in browsers, this 20ms headstart is
likely irrelevant as the VM can be already be started before the first code is
received.

It would be nice to see some start up benchmarks using larger applications, so
that improved start up time vs V8, can be evaluated. Perhaps using a large Dart
application, built with dart2js, running on V8, and comparing against the start
up time on the Dart VM is the way to go?
