javascript - 慢咕噜 watch

Question

我已经在 Windows 7 Professional 系统上设置了一个简单的 grunt 环境。这是我创建的 gruntfile.js:

module.exports = function(grunt) {

	grunt.loadNpmTasks('grunt-contrib-compass');
	grunt.loadNpmTasks('grunt-contrib-watch');
	grunt.loadNpmTasks('grunt-sftp-deploy');

	grunt.initConfig({
		pkg: grunt.file.readJSON('package.json'),
		'sftp-deploy': {
			build: {
				auth: {
					host: '',
					port: 22,
					authKey: ''
				},
			cache: 'sftpCache.json',
			src: '/css',
			dest: '/public_html/css',
			exclusions: ['/css/**/.DS_Store', '/css/**/Thumbs.db', 'dist/tmp', '/css/dev', '/css/*.map'],
			serverSep: '/',
			localSep: '/',
			concurrency: 4,
			progress: true
			}
		},
		compass: {
			dist: {
				options: {
				sassDir: '/css/dev',
				cssDir: '/css',
				environment: 'production'
				}
			},
			dev: {
				options: {
				sassDir: '/css/dev',
				cssDir: '/css'
				}
			}
		},
		watch: {
			css: {
				files: '**/*.scss',
				tasks: ['compass:dev']
			},
			ftp: {
				files: 'css/*.css',
				tasks: ['sftp-deploy']
			}
		}
	});

	grunt.registerTask('default',['watch']);

}

如果我启动 grunt，一切都会正常，但速度很慢。完成这三项任务最多需要 15 秒:

slow grunt

我是不是做错了什么？

By default this watch task will spawn task runs as child processes. For some systems, especially on Windows it can be really slow. Set the option: nospawn: true.
