jmeter性能分析

Question

我正在为perf环境运行性能测试。

结果如下：

CPU Utilization

Server  Apdex   Resp. time  Throughput  Error Rate  CPU usage   Memory
per001205       0.970.5     220 ms      2,670 rpm   0.0009 %    493.00% 2.2 GB
per001206       0.950.5     280 ms      2,670 rpm   0.0043 %    516.00% 2.4 GB
per011079       0.830.5     526 ms      2,670 rpm   0.0034 %    598.00% 2.5 GB
per011080       0.670.5     1,110 ms    2,670 rpm   0.0026 %    639.00% 2.6 GB

你能评论一下平均响应时间是怎样的吗？它被接受了吗？我看到CPU使用率超过100%，危险吗？

我应该如何改进这一点？我为250个用户运行它。

• Consider首先查看

1. 的其他监控方法，即直接转到主机，通过操作系统内置命令检查CPU usage mismatch or usage over 100%的使用情况，或者使用JMeter PerfMon plugin确认图片或获得CPU负载的替代视图。根据结果，您有两个选项：

- Either individual servers CPU usage is acceptable and you can decide whether throughput good or not
- Or you need to fix the issue in your application code: using [profiling tools](https://en.wikipedia.org/wiki/Profiling_(computer_programming%29) for the programming language, your application is written in detect the most CPU intensive functions and refactor them to be less processor-time-hungry
