php - Guzzle HTTP 客户端比 Symfony HTTP 客户端慢

Question

这可能是基于意见的问题。

我想用Guzzle HTTP Client许多人认为它比 Symfony HTTP Client 更好, 还有 Cloudflare在其 PHP Api 中使用 Guzzle HTTP 客户端.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 Guzzle HTTP Client 如此有名气却缺乏速度。或者我做错了什么。

Change 1

更新:

我在 test.php 中编辑了我的代码到

包括 PHP Curl。

为多个并流请求添加了循环。

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

正确重置所有变量，而不仅仅是重新分配。

发现:
更改代码后，时间上有很大差异。然而，尽管 this 仍然对为什么会发生这种情况感到困惑被指给我看。

但最终因为 Guzzle HTTP Client 的时间(看起来很现实)接近 PHP Curl，并且因为 Guzzle HTTP Client 处理 HTTP 错误与 Symfony HTTP Client 不同，并且在获取 url 时抛出异常而不是在获取结果时抛出异常。

我认为 Guzzle HTTP Client 比 Symfony HTTP Client 更适合我的项目。

Answer 1

那是因为 Symfony 客户端不是在 $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，您应该已经注意到之前的时间是不可能实现的。

我在修复之前的测试在哪里
Symfony:0.00944495201
Guzzle :0.18365287780

Symfony 结果比任何简单的网络 ping 都要快
