我正在尝试制作一个包含多个相同 SWF 的网页。我遇到的问题是加载速度太慢（不过下载时间还不错）。我的每个单元格中有一个 4x4 表格，iframe 中嵌入了一个 swf 文件。（注：4 X 4 表 => 16 SWFS）.
我的 AS3 代码非常简单：
package
{
import flash.display.Sprite;
import flash.system.System;
import flash.text.TextField;
public class ActionscriptProject extends Sprite
{
public function ActionscriptProject()
{
var txt:TextField = new TextField();
txt.x=0;
txt.y=0;
txt.width=5000;
txt.height=5000;
addChild(txt);
txt.htmlText+="<font size='45'>"+System.totalMemory/1048576 + " MB"+"</font>";
}
}
}
我使用以下 html 将其加载到 iframe 中：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Flash Testing</title>
</head>
<body>
<table border="1">
<tr>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
</tr>
<tr>
...
</tr>
<tr>
...
</tr>
<tr>
...
</tr>
</table>
</body>
</html>
注意：ActionscriptProject.html 只是 Flash Builder 使用应用程序创建的标准 html。但应 The_asMan 的要求，我将其包含在这里：

在 Chrome 中没有问题。所有应用程序加载速度都非常快（我估计在 3 秒内）。
在 IE 8 中这个问题很小。
在 IE 7 和 Firefox 3.6.17 中，页面加载需要很长时间。我没有在其他浏览器中测试过。
在 Firefox 中，页面加载大约需要 34 秒。
总共System.totalMemory据报道，swf 使用的总内存约为 42 MB。

您是否尝试过构建一个容器 swf，它本身会加载其他 swf？这可能会更快，因为这样 Firefox 就不必一次又一次地处理初始化 swf 的开销。创建一个空白电影来加载一堆其他电影并将它们放置在网格中是相当简单的。
