Martin Kustermann e171ff4a6d [vm/concurrency] Speed up isolate communication via normal snapshotting
Do not lock forwarding table during snapshot writing:

This is a follow-up to [0], which made the [WeakTable] used during
snapshot writing per isolate. Since each isolate has it's own table
now, there's not reason to lock it during snapshot writing.

Furthermore we speed up RawObject::InVMIsolateHeap() which was super slow
due to locking "vm-isolate"'s page space and walking all pages.

Dart

A client-optimized language for fast apps on any platform

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 has 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).
