我正在尝试建立我的网站，我是新手，但我曾尝试将此代码用于背景幻灯片，不幸的是，加载页面需要很长时间。我已将 3-500KB 的图像优化为现在的 90-100KB，但仍然需要很长时间才能加载...帮助！
我的网站的更新版本。我正在尝试使用我在网上找到的这些提示使其加载更快，但我很难让它加载得足够快。
- 我的 CSS 文件（太大而无法发布）。
- 我的 HTML 页面无法在此处发布，它似乎不起作用

在检查时，您正在加载的图像似乎太多了，而且一下子就使网站变慢了。
( http://i.stack.imgur.com/xPRxM.png )
您应该使用延迟加载来更快地加载站点，因为这样只会加载所需的图像。
在需要时请求图像（或者可能在需要之前一点），但您绝对不应该将所有请求放在一起。
其次，你应该有不同的图像尺寸，根据需要准备好，而不是让浏览器调整图像的大小。它消耗时间和处理来让浏览器调整图像大小。如果你有图像的副本，它会让生活更简单。
有很多插件可用于实现延迟加载。由于您使用的是 jQuery，因此这里有一些：
- http://www.appelsiini.net/projects/lazyload （这里有简单的演示）
- http://css-tricks.com/snippets/javascript/lazy-loading-images/
- http://www.google.com/search?q=lazy+loading+jquery
其他提示：
将所有脚本合并为一个，并制作一个js文件。
因此，以下内容：
- <script type="text/javascript" src="js/pop-ups.js"></script>
- <script type="text/javascript" src="js/jquery.easing.1.3.js"></script>
- <script type="text/javascript" src="js/jquery.mousewheel.js"></script>
- <script type="text/javascript" src="js/jquery.jscrollpane.min.js"></script>
- <script type="text/javascript" src="js/cufon.js"></script>
变成<script type="text/javascript" src="js/all.js"></script>
现在，为了进一步优化，缩小它们。
有很多在线工具，但我喜欢这个。
另外，我建议您看一下Chris Coyier 的演示文稿（从幻灯片 97 开始）。

@Pranav 的回答非常好。
你绝对应该看看 chrome 检查器拥有的所有工具（我确定是 firefox）
加载您的网站会给我 94 个错误。
你需要看很多东西，但我肯定会推荐使用 css sprites，特别是对于那些疯狂数量的图片。
您需要最小化请求。看看我在说什么。
这是 chrome 审核告诉您的网站的内容，您不需要执行所有这些操作，但您应该尝试执行以下操作：
Combine external JavaScript (16)
There are multiple resources served from same domain. Consider combining them into as few files as possible.
8 JavaScript resources served from globalplayernetwork.com.
5 JavaScript resources served from maps.gstatic.com.
3 JavaScript resources served from maps.google.com.
Enable gzip compression (20)
Compressing the following resources with gzip could reduce their transfer size by about two thirds (~668.95KB):
in.html could save ~10.15KB
style.css could save ~12.02KB
jquery.min.js could save ~46.99KB
pop-ups.js could save ~4.91KB
jquery.easing.1.3.js could save ~3.54KB
jquery.mousewheel.js could save ~881B
jquery.jscrollpane.min.js could save ~9.52KB
cufon.js could save ~14.03KB
Quicksand_Book_400.font.js could save ~17.13KB
functions.js could save ~2.10KB
jquery.mCustomScrollbar.js could save ~8.67KB

mod_svau.js could save ~2.14KB

maps.google.com/cbk?output=xml&hl=en&ll=36.131931,-115.160451&cb_client=&v=4 could save ~659B
