Php Guzzle HTTP客户端比Symfony HTTP客户端慢

这可能是基于意见的问题。

我想使用尽可能多的建议，它比，也使用Guzzle HTTP客户端在其。但是，我使用SymfonyHTTP客户端和Guzzle HTTP客户端执行了一个简单的测试。结果表明Guzzle HTTP客户端比Symfony HTTP客户端慢得多

我想知道/理解为什么拥有如此著名声誉的HTTP客户端缺乏速度。或者是我做错了什么

composer.json

test.php

操作系统和其他详细信息

Ubuntu18.04.4 LTS在Windows10版本1909的HyperV中

Curl版本7.58（7.58.0-2ubuntu3.8）

PHP版本7.4.5（7.4.5-1+ubuntu18.04.1+deb.sury.org+1）

PHP FPM版本7.4（7.4.5-1+ubuntu18.04.1+deb.sury.org+1）

PHPCurl版本7.4（7.4.5-1+ubuntu18.04.1+deb.sury.org+1）

变化1

更新：

我已经在

test.php

中将我的代码编辑为

混合使用PHP Curl

增加了多个同流请求的循环

使用本地网络上另一台服务器的地址作为测试站点，因为许多站点将阻止多个并发请求

正确重置所有变量，而不只是重新分配

查找： 更改代码后，时间上有很大的差异。然而，即使有人向我指出了这一点，我仍然对为什么会发生这种情况感到困惑

但最终，由于Guzzle HTTP客户端的计时（看起来很现实）接近PHP Curl，并且由于Guzzle HTTP客户端处理的HTTP错误与Symfony HTTP客户端不同，因此在获取url时而不是在获取结果时抛出异常

---

我认为Guzzle HTTP客户端比Symfony HTTP客户端更适合我的项目。

这是因为Symfony客户端不在$HTTP->request（）上执行请求。 这是在第一次需要时完成的

当您更改两个测试用例的代码时，您会看到时间差消失了

当检查你的结果是否可信时，你应该注意到以前的时间是不可能实现的

修复前的我的测试，其中
Symfony:0.00944495201
狂饮：0.18365287780

---

Symfony结果比任何简单的网络ping都快

当_curlG在_curlS之前时，结果是否相同？我已经交换了函数定义，测试代码也一样。最终的结果仍然是Guzzle比Symfony慢。vanilla curl的表现如何？基准测试很难获得正确的结果，而且结果通常是毫无用处的。使用这两种方法实现你的应用程序，然后分析你的日志。性能是否会有显著差异？这两种方法都在后台使用curl，因此，如果你在其中任何一种方法中获得的时间都比香草curl快，那么好的答案就有问题了。如果它对任何人都有帮助，请注意，如果不从

\u curlS

返回任何内容，您将看到相同的准确结果-Symfony响应类也会在超出范围时通过

\u destruct

方法进行解析。
