nginx+lua+redis

上次测试完之后，觉得这个代码还有提高的空间，于是查了下怎么在golang中使用redis连接池（其实就是redigo的使用），还有lua中怎么使用redis连接池（其实就是rest.redis的使用）。

先上结果:

openresty + lua + redis

Concurrency Level:      100
Time taken for tests:   0.284 seconds
Complete requests:      1000
Failed requests:        0
Total transferred:      687000 bytes
HTML transferred:       531000 bytes
Requests per second:    3522.03 [#/sec] (mean)
Time per request:       28.393 [ms] (mean)
Time per request:       0.284 [ms] (mean, across all concurrent requests)
Transfer rate:          2362.93 [Kbytes/sec] received

再看golang:

golang + redis

Concurrency Level:      100
Time taken for tests:   0.327 seconds
Complete requests:      1000
Failed requests:        0
Total transferred:      650000 bytes
HTML transferred:       532000 bytes
Requests per second:    3058.52 [#/sec] (mean)
Time per request:       32.696 [ms] (mean)
Time per request:       0.327 [ms] (mean, across all concurrent requests)
Transfer rate:          1941.44 [Kbytes/sec] received

golang中除了添加了线程池，还设置了cpu核数。

不过这个测试并不十分严谨，redis，nginx，golang http server，ab压测都在一台机器，相互之间会有影响。有兴趣的可以自己分开部署测试下。

以上就介绍了nginx+lua+redis，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
