Nginx与Tomcat作为前端服务器的性能比较


摘要

最近总遇到使用tomcat还是使用nginx进行前端文件访问的争论
想着出差周末在酒店, 可以自己进行一下简单的测试. 
希望能够对未来的工作进行一些指导. 

测试脚本

30KB 文件测试
ab -c 1000 -n 50000 -k http://127.0.0.1:5201/index.html
7.5MB 文件测试
ab -c 1000 -n 50000 -k http://127.0.0.1:5201/zhaobsh.html

简要测试结果

TPS的比较, 值越大越好

文件大小 tomcat-TPS nginx-TPS
20KB 44094 66418
7.5MB 585 672

响应时间的比较, 值越小越好

文件大小 tomcat-RT nginx-RT
20KB 22.679 15.056
7.5MB 1708.946 1488.010

测试结果简要分析

Nginx在处理静态文件 在比较零散时 应该至少比tomcat要好 50%
但是如果有网络瓶颈时, 可能不会有这样的效果
但是同时发现. java会开启大量的http线程进行相应
内存占用会比较高, 一个线程至少1MB的栈区.
同时发现JVM几乎不会有堆区GC的现象. 

另外nginx在进行压测时CPU的使用量是很低. 压测java时CPU是能到 30%
但是nginx的CPU使用量比较低. 

详细结果信息

说明: 配置相同
tomcat: 采用产品直接运行的界面进行测试
nginx:  采用将文件放到 html目录下面进行测试
测试说明 30KB小文件和 7.5MB的大文件. 
直接在物理机器上面进行测试

使用tomcat直接进行测试

1000个连接 五万个请求时

tomcat的压测情况

压测之前:
-                    Thread (reserved=242MB, committed=242MB)
                            (thread #241)
                            (stack: reserved=241MB, committed=241MB)
                            (malloc=1MB #1210) 
压测时: 
-                    Thread (reserved=390MB, committed=390MB)
                            (thread #387)
                            (stack: reserved=387MB, committed=387MB)
                            (malloc=1MB #1940) 
                            (arena=1MB #769)

注意 这是 tomcat 的配置事项:
  tomcat:
    threads:
      max: 500
    accept-count: 1000
    max-connections: 20000
    connection-timeout: 60000

但是需要注意, 仅使用前端, 几乎不会带来GC的现象. 
线程会有所增加, 应该是提高了 http的工作线程.
