Question

我正在尝试对我的其余API端点的性能进行基准测试。它是一个node / mongdb端点，带有非常讨厌的聚合查询 - 一些unwraps，group和lookup。我正在使用Apache Bench（ab）来测试它在100次并发1000次下的性能。我的问题：我根据运行ab测试的位置得到了不同的结果：

localhost：3000 / api_endpoint /使用ngrok隧道它=我每秒大约50个请求。
运行测试生产应用程序服务器直接在我看到应用程序的软管每秒6000个请求。
从我的Web服务器/反向代理运行它我每秒看到类似5000reqs - 如果我使用API的相对路径。
现在：如果我在网络服务器上运行相同的测试但这次使用域名或从本地dev运行它机器，但击中域，现在它下降到每个9个请求第二

我可以推断出什么？对我来说，如果我直接点击它时获得如此高的性能，那么查询似乎不应该是那么讨厌。我的nginx.conf文件中有一些配置错误，用于处理我的域请求或者存在DNS解析问题？它是一个充满异国情调的顶级域名（.ly）可能是它吗？我应该在哪里看？

编辑：添加我的nginx.conf文件进行分析：
