半连接队列和全连接队列-定时拉起APP之后的一些思考(三)

两个队列，半连接队列和全连接队列。两个状态，SYN_SENT、SYN_RECV

netstat -np | grep SYN

worker_processes 1;


events {
    worker_connections 1024;
}


http {
    server {
        listen 28090 backlog=16;


        location = /cent {
            content_by_lua_block {
                local index = 0
                for i = 0, 1000 * 1000 do
                    for j = 0, 1000 do
                        for k = 0, 5 do
                            index = index + 1
                        end
                    end
                end
                ngx.say("ok\t", index)
            }
        }
    }
}

netstat -np | grep -c SYN_REC
