When configuring many nodes execution time can be very long, as nodes will be configured sequentially. There should be an option to configure nodes in parallel, which would achieve a big speedup.

Fabric implements parallel execution of tasks in version 1.3.

Knife's ssh command has a concurrency option:
-C, --concurrency NUM The number of concurrent connections

LittleChef could mimic that syntax.

  • fix -C 4 node:all
  • fix --concurrency=4 node:all

both should configure all nodes using 4 parallel threads. There could be a default number so that
fix -C node:all works as well.
