By default, [https://github.com/gruntjs/grunt-contrib-watch grunt-contrib-watch] uses a 100ms interval. Several of the groups in our `_watch` config specify an interval of 2 seconds, but others defer to the default. In my local environment (non-VM), if I add `options: { interval: 2000 }` to the config, colors, test, and phpunit groups, `grunt watch` CPU usage stays consistently within 2 to 5% at idle. See [https://github.com/gruntjs/grunt-contrib-watch/issues/429 this related discussion on the grunt-contrib-watch project ] If I change all configurations to 1 second, `grunt watch` CPU usage stays at around 9%. I'm attaching a patch that applies only the interval addition to each of the other groups." defect (bug) closed normal 5.1 Build/Test Tools normal fixed has-patch
