什么是“封锁"?真的意味着在Firefox开发人员工具中进行网络监控? [英] What does "Blocked" really mean in the Firefox developer tools Network monitoring?

问题描述

Firefox网络监视器文档的定时部分， 阻止"的解释为:

The timing section of the Firefox Network Monitor documentation, "Blocked" is explained as:

在队列中等待网络连接所花费的时间.

Time spent in a queue waiting for a network connection.

浏览器对可以连接到单个服务器的同时连接数施加了限制.在Firefox中，默认值为6

The browser imposes a limit on the number of simultaneous connections that can be made to a single server. In Firefox this defaults to 6

对连接数的限制是唯一的限制吗?还是浏览器被阻止，等待从操作系统获取连接也被视为被阻止?

Is the limit on the number connections the only limitation? Or is the browser blocked waiting to get a connection from the OS count as blocked too?

在一个新的浏览器中，在第一个连接上，在进行任何其他连接之前(因此限制在此处不适用)，我被阻止了195毫秒.

In a fresh browser, on a first connection, before any other connection is made (so the limit should not apply here), I get blocked for 195 ms.

这是浏览器在等待操作系统吗? 封锁"在这里是什么意思?

Is this the browser waiting for the OS? Was does "Blocked" mean here?

推荐答案

在队列中等待网络连接所花费的时间.

Time spent in a queue waiting for a network connection.

浏览器对并发连接数施加限制 可以在一台服务器上完成.在Firefox中，默认值为6， 但可以使用 网络.http.max-persistent-connections-per-server偏好设置.我摔倒 连接正在使用中，浏览器无法下载更多资源 直到连接被释放.

The browser imposes a limit on the number of simultaneous connections that can be made to a single server. In Firefox this defaults to 6, but can be changed using the network.http.max-persistent-connections-per-server preference. If all connections are in use, the browser can't download more resources until a connection is released.

很明显，浏览器将限制限制为每个服务器6个并发连接(域/IP)，操作系统问题不是很重要.

It's very clear that the browser fixes the limit to 6 concurrent connections per server (domains/IP), the OS question is not very relevent.
