iFrame中并行不执行 [英] iFrames not executing in parallel

问题描述

我们正在使用我们的网页上的iFrame中6。他们从几个外部Web服务和内部WCF服务获取数据并显示数据。有每个iFrame中内置一个独立的aspx页面。从我们监测PERF我们发现，在任何时候只有两个线程并行执行。并非所有6个线程得到执行。有什么可以可能是导致此？有没有超过2个线程不能并行创建任何限制？是否有任何配置，我可以改变这个？

We are using 6 iFrames on our page. They fetch data from couple of external web services and an internal WCF service and display the data. There is a separate aspx page built for each of the iFrames. From our perf monitoring we found out that at any point only two threads are executing in parallel. Not all 6 threads get executed. What can probably be cause for this? Is there any restriction that more than 2 threads can't be created in parallel? Is there any configuration where I can change this?

推荐答案

这是 IE6 和 IE7 的真。无关的DNS。为了模拟这一点，在IE浏览器同时运行三个以上的下载，你会发现只有两个在执行一次，其余的将等待。不同的情况下使用Firefox，我相信这是6 - 值得检查

This is true of IE6 and IE7. Nothing to do with DNS. To simulate this, run three or more downloads simultaneously in IE and you will find that only two at a time are executed, the rest will wait. Different case with Firefox, which I believe is 6 - worth checking.
