Guzzle HTTP Client 比 Symfony HTTP Client 慢

Question

这可能是基于意见的问题。

我想使用 Guzzle HTTP Client as many suggest that its better than Symfony HTTP Client, also Cloudflare uses Guzzle HTTP Client in its PHP Api。但是，我使用 Symfony HTTP Client 和 Guzzle HTTP Client 执行了一个简单的测试。结果表明 Guzzle HTTP Client 比 Symfony HTTP Client 慢得多。

我想知道/理解为什么享有如此盛名的 Guzzle HTTP Client 缺乏速度。还是我做错了什么。

Change 1

更新：

我已将 test.php 中的代码编辑为

将 PHP Curl 加入组合。
为多个并发请求添加了循环。
使用本地网络上另一台服务器的地址作为测试站点，因为许多站点会阻塞多个并发请求。
正确重置所有变量，而不是仅仅重新分配。

发现： 更改代码后的时间差异很大。但是，即使有人向我指出了，我仍然对为什么会发生这种情况感到困惑。

但最终 Guzzle HTTP 客户端的计时（这看起来很现实）接近 PHP Curl，并且 Guzzle HTTP 客户端处理 HTTP 错误的方式不同于 Symfony HTTP 客户端并抛出异常在获取 url 而不是在获取结果时。

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

Answer 1

那是因为 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，您会发现时差消失了

...
$response = $http->request($method, $url, $httpOpt);
return $response->getStatusCode();

在检查结果的合理性时，您应该注意到以前的时间是不可能达到的。
