HI：all
目前我们用openresty搭建了 后端api，
自己写了一个 机遇lua-table 写的面向对象的 framework，
每台服务每天访问量5000万，精确统计了qps，最高2600，cpu均值超过60%，
8 local a = {}
9
10 local b= {
11 a=12,
12 c='dasda',
13 f='test'
14 }
15
16 --local a = require "cjson"
17 table.insert(a,b)
18
19 ngx.print(1);
lua_code_cache off ;
ab压力测试 ab -c 10 -n 1000 "http://192.168.10.30:8085/test"

而启用require函数，ab -c 10 -n 1000 "http://192.168.10.30:8085/test"

经查找原因是 require函数的问题。
