ab apache 基准测试中的传输速率

Question

我正在对用 SpringBoot 编写的简单 helloworld app written in my framework against the one 进行基准测试。

SpringBoot版本的ab日志：

正如我们所见，每秒的事务处理量几乎相同。但是传输速率非常不同。 SpringBoot版本超过4.5Kb/s，Act版本只有2.7Kb/s

我不知道

为什么响应时间几乎相同，而传输速率却相差如此之大？
如何提高传输速率？我正在使用 undertow 作为我的网络层，我应该做些什么来调整 undertow 吗？ Here 是我创建 undertow 网络层的代码

Answer 1

处理的请求数量相同，但响应在内容和 HTTP 中都不同 headers。因此流量也有差异。
