Run Tasks in Parallel	Learn how to configure Nx to run multiple tasks simultaneously by adjusting the parallel option in the command line or nx.json configuration.

Run Tasks in Parallel

If you want to increase the number of processes running tasks to, say, 5 (by default, it is 3), pass the following:

npx nx build myapp --parallel=5

You can also set parallel based on the percentage of the number of logical CPUs.

npx nx build myapp --parallel=50%

Note, you can also change the default in nx.json, like this:

{% tabs %} {% tab label="Nx >= 17" %}

{
  "parallel": 5
}

{% /tab %} {% tab label="Nx < 17" %}

{
  "tasksRunnerOptions": {
    "default": {
      "runner": "nx/tasks-runners/default",
      "options": {
        "parallel": 5
      }
    }
  }
}

{% /tab %} {% /tabs %}
