Jquery函数和使用cpu加载100％

Question

我把我的代码清理干净，知道问题以及为什么当加载cpu得到100％时，我在firefox和其他导航器中看到chrome问题cpu 100％当网站加载这个动画时，我不知道是什么'不好但只在加载这个网站和这个动画时发生

$.fn.stars=function(settings) {
        var config = {
            'i' : '',    // image URL
            'c' : 50,    // clear: radius around the mouse to not fill with stars
            'd' : .00005,// density: how many stars per pixel to show - KEEP IT LOW!
            'm' : 100,    // maximum size of stars
            's' : 1000,  // speed (in ms) of star appearance
            'l' : 2000,  // length of time star stays on page
            'f' : 2000,  // fading time
            'h' : 2000   // max hide time before a star appears again somewhere else
        };

请我尝试知道它有什么不好，我向人们提供帮助以了解问题或解决此问题的最佳配置
