The SDK is shipped with a standalone version of the VM which can do I/O (via the 'dart:io' package). You can use it to write command line applications and web servers. Basically, it's like Node right off the bat.

I/O performance increased drastically with 1.3. The performance is tracked over here:

1.4 added experimental support for ServerSocket references, which allow you to share a socket across isolates (~"workers"):

The round-9 techempower benchmark shows Dart as very impressive in its "Multiple Queries" runs. However, the json serialization not so much. Is there something in the works to speed this up or technical reasons it does not shine here? Also, what are the plans for speeding up regular expresssions?

With Dart 1.5 announced, I am interested in ensuring that Round 10 includes 1.5. I just posted a question [1] to our most active Dart test contributor: does the >= 1.3.0 specified in the pubspec.yaml ensure that we'll be testing on 1.5 in Round 10 or should we be more explicit about 1.5.0? If anyone else knows the answer I'd appreciate the feedback.

It will just cause a `pub get` fail (Package foo requires SDK version >=1.5.0 but the current SDK is x.x.x), but it won't prevent the application from running. Only `pub` cares about that pubspec.yaml file.
