加载多个TinyMCE实例会冻结浏览器，解决方案

我有一个页面，多个时间实例同时运行，每次加载时都会冻结浏览器。在我再次使用浏览器之前，等待时间不少于15秒。我已经在IE9, FF6和Chrome上测试过了，所有这些都在加载时冻结了一段时间。

我怎样才能防止这种冻结的发生?我至少有10个文本区域与时间连接到它在一个页面。计算机在core2duo上运行，内存为4GB，没有任何其他程序运行，但这应该无关紧要，因为即使在较低规格的PC上也应该可以工作。

编辑添加JS代码来加载TinyMCE。

<script type="text/javascript">
var myTextbox = "10 name of textarea here";
tinyMCE.init({
    // General options
    mode : "exact",
    elements: myTextbox,
    theme : "advanced",
