Web 浏览器性能规则是“每个主机名只有 2 个并行请求"吗?仍然正确吗? [英] Is the web browser performance rule "only 2 requests in parallel per hostname" still correct?

问题描述

Steve Souders 在他的高性能网站"一书中(2007 年)写道，浏览器将对域/主机名的并行请求限制为一次两个.这在今天仍然有效吗?

In his book "High Performance Websites" Steve Souders wrote (2007) that browsers limit parallel requests to a domain/hostname to two at a time. Is this still valid today?

推荐答案

今天几乎不正确.

大多数浏览器已升级到 6 个并行连接.请参阅 Steve Souder 的 Browserscope > 网络选项卡 > 每个主机名的连接数.旧版浏览器仍限制为 2 个连接 - 这可能与您相关，也可能与您无关，具体取决于您的应用程序支持的浏览器.

Most browsers have upgraded to 6 parallel connections. See Steve Souder's Browserscope > Network tab > Connections per Hostname. Older browsers still restrict to 2 connections - that may or may not be relevant to you depending on the browsers your application supports.
