Question

我使用embed jetty / tomcat加载测试spring boot应用程序，我的行为很奇怪。我使用apache ab进行测试

ab -n 100000 -c 1000 http://127.0.0.1:8080/ping

Server Software:        
Server Hostname:        127.0.0.1
Server Port:            8080

Document Path:          /ping
Document Length:        2 bytes

Concurrency Level:      1000
Time taken for tests:   5.253 seconds
Complete requests:      100000
Failed requests:        0
Total transferred:      17000000 bytes
HTML transferred:       200000 bytes
Requests per second:    19038.05 [#/sec] (mean)
Time per request:       52.526 [ms] (mean)
Time per request:       0.053 [ms] (mean, across all concurrent requests)
Transfer rate:          3160.61 [Kbytes/sec] received

Connection Times (ms)
              min  mean[+/-sd] median   max
Connect:        0   37 222.1      0    3006
Processing:     0    7  21.9      3     855
Waiting:        0    7  21.7      3     853
Total:          0   44 228.0      4    3052

Percentage of the requests served within a certain time (ms)
  50%      4
  66%      7
  75%      9
  80%     11
  90%     22
  95%     39
  98%   1004
  99%   1017
 100%   3052 (longest request)

所以有些请求被卡在某处有了码头，我尝试了不同的价值观：

_maxThreads, _minThread

与tomcat：

max-connections, max-threads, min-spare-threads

在分析器中我找到了下一个：

org.eclipse.jetty.util.thread.QueuedThreadPool$2.run()                16,215ms
    org.eclipse.jetty.util.thread.QueuedThreadPool.access$800
        org.eclipse.jetty.util.thread.QueuedThreadPool.iddleJobPoll
            org.eclipse.jetty.util.BlockingArrayQueue.poll            13,915ms

谢谢！

最后，我找到了答案。有些问题每30秒发生一次。

load test

这是因为“server：tomcat：background-processor-delay”param。

Spring启动负载测试：一些请求卡住了
