SpringBoot 内置 Tomcat 线程数优化配置本文解析springboot内置tomcat调优并发线程数的一些参数，并结合源码进行分析。tomcat主要通过使用自己的TaskQueue队列来对线程池做出了不同的策略，也就是tomcat当线程数大于核心数时就会直接创建新的线程来处理，而不是放到队列。阅读详情

使用jmeter进行测试，
发现进程数到达一定的数量之后就不会在变化了。

[root@localhost ~]# pstree -p 3793 |wc -l
219
[root@localhost ~]# pstree -p 3793 |wc -l
219
[root@localhost ~]# pstree -p 3793 |wc -l

[root@localhost ~]# pstree -p 3793 |wc -l
