[CFE] Benchmarker tool using perf stat Tool that runs two or more aot-snapshots in the same way through perf stat, then performing statistics on the result. This generally runs ``` perf stat -B taskset -c 7 out/ReleaseX64/dart-sdk/bin/dartaotruntime \ --deterministic <snapshot> <arguments> ``` a number of times, doing statistics on the data from `perf stat`. Note that this makes it only run on 1 core as that seems a little more stable, though it's normally not necessary. The `--deterministic` is necessary though.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
