httpwatch 或firebug测试得到blocked时间超长，HTTPWATCH中说明blocked为
The Blocked time includes any pre-processing time (such as cache lookup) and the time spent waiting for a network connection to become available. Internet Explorer will only create a maximum of two concurrent network connections per host name (i.e. www.microsoft.com) and will queue up requests until a network connection is available. Often the Blocked time is the most significant factor in the download time of images embedded in a web page.

闭塞时间，包括所有的过程之前的时间（像，cache对比）和等待网络链接的时间，IE在每个主机名（像www.microsoft.com）下最多只创建两个当前的网络连接，而且要排队等待直到这个网络链接可用，通常，闭塞时间影响网页中图片加载时间的重要因素。
但感觉太模糊了，有没有具体的说明
