background option cause the node consume too much CPU

[ghost]

If I set the background:true, the node will consume almost 35%~46% of my CPU.

my config:

express: {
    options: {
    port: 8080,
            debug: true,
            background: true,
            delay: 2000
        },
        dev: {
            options: {
                script: "app.js"
            }
        }
},

That's interesting. By default, background is true, so that the server runs in it's own process.

I'm running the following now from master:

$ grunt express:defaults watch

The first one is the Grunt + watch, while the 2nd one is the server itself.

Is it the complexity of your application, or is it because the watch task is watching tons of files? You can test this by setting background: false on your app (which is the equivalent of just running node ./path/to/server.js) and take a screenshot of the difference.

Closing until someone can help me replicate the issue...
