ruby-on-rails – 在日本应用程序中,Grunt任务很慢

一切都很好,除了咕噜咕噜的任务很慢.

当我运行grunt服务器时–verbose：

Execution Time (2014-01-15 13:37:55 UTC)

watch                  5.8s  ▇▇▇▇▇▇▇▇▇ 11%

我的一些Gruntfile：

'use strict';
module.exports = function (grunt) {
  require('time-grunt')(grunt);
  require('load-grunt-tasks')(grunt);
  require('time-grunt')(grunt);

  grunt.initConfig({
    ...
  });

grunt.loadNpmTasks('grunt-preprocess');

  grunt.registerTask('server',function (target) {
    if (target === 'dist') {
      return grunt.task.run(['build','connect:dist:keepalive']);
    }

    grunt.task.run([
      'preprocess:multifile','clean:server','concurrent:server','autoprefixer','connect:livereload','watch'
    ]);
  });

  grunt.registerTask('test',[
    'clean:server','concurrent:test','connect:test'
    //'karma'
  ]);

  grunt.registerTask('build',[
    'preprocess:multifile','clean:dist','useminPrepare','concurrent:dist','concat','copy:dist','cdnify','ngmin','cssmin','uglify','rev','usemin'
  ]);

  grunt.registerTask('default',[
    'jshint','test','build'
  ]);

};

项目规模：

vagrant@vm ~code/myapp/app/scripts
$> find -name "*.js" | xargs cat | wc -l

我在MacOS 10.8上使用i7处理器,16GB内存,SSD …这是正常的,需要这么长时间？是什么让笨蛋任务(尤其是“加载任务”)如此缓慢？

注意：我在一个流浪汉机器内ssh’d并从那里运行grunt命令.如果我在我的本机系统上运行grunt命令,它会更快(加载任务需要1.6s而不是14.3).

所以共享文件系统可能是个问题.但为什么…
