JMeter 恒定吞吐量计时器未达到所需的 TPS

  • 772

我有一个 JMeter 测试计划，其中添加了一个虚拟采样器和一个作为其子项的恒定吞吐量计时器。我想实现 10 TPS 的目标，因此我将吞吐量设置为每分钟 600 个样本，用户 - 10。但是，运行测试后，我预计它会达到 10 TPS，但其性能不如预期。有人能帮我找出我可能做错了什么吗？

    平均响应时间为276毫秒，这意味着1个用户每秒可以发出3.62个请求，10个用户每秒将发出36个请求。

    如果你需要每秒 600 个请求，则需要将数量增加到 166+

    您还可以查看吞吐量塑造计时器和并发线程组的组合，它们可以通过反馈功能连接在一起，这样，如果当前数量不足以实现所需的吞吐量，JMeter 将能够启动额外的线程。
