发布一个python服务框架iserver（带压力测试数据）
Iserver简介Iserver是一个用python编写的网络服务框架（编译版本3.4.1），使用的是epool网络模型
测试机配置
处理器 2x Genuine Intel(R) CPU T2050 @ 1.60GHz
内存 2060MB (673MB used)
nginx开启进程数
root 2413 2409 0 09:17 pts/0 00:00:00 grep -i nginx
www 2414 2411 2 09:17 ? 00:00:00 nginx: worker process
www 2415 2411 0 09:17 ? 00:00:00 nginx: master process
www 2416 2411 0 09:17 ? 00:00:00 nginx: master process
www 2417 2411 0 09:17 ? 00:00:00 nginx: master process
www 2418 2411 0 09:17 ? 00:00:00 nginx: master process
www 2419 2411 0 09:17 ? 00:00:00 nginx: master process
www 2420 2411 0 09:17 ? 00:00:00 nginx: master process
www 2421 2411 0 09:17 ? 00:00:00 nginx: master process
开启8个nginx进程消耗120M内存（15M * 8 = 120M）
php-cgi 开启进程数
root 2424 1 0 09:17 ? 00:00:00 php-fpm: master process
www 2425 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2426 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2427 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2428 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2429 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2430 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2431 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2432 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2433 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2434 2424 0 09:17 ? 00:00:00 php-fpm: pool www
www 2435 2424 0 09:17 ? 00:00:00 php-fpm: pool www
开启12个php-cgi进程消耗掉240M内存（20M * 12 = 240M）
测试流程
首先启动队列网络服务，php向队列服务里插入一条insert sql，例如
client.php
1 /**
2* socket client
3* a NULL填充字符串
4* n 表式无符号短整形
5* 无符号短整型, 总是16点，大端字节序
6*/
7 function insert_queue($cmd, $sql) {
8 $s = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
9 try {
10 socket_connect($s, "127.0.0.1", 8888);
11 $list = json_encode(array(
12 "sql"=>$sql
13 ));
14 $len = strlen($list);
15 $param = pack("nna{$len}",$cmd, $len, $list);
16 socket_write($s, $param, strlen($param));
17 socket_recv($s, $head, 4, 0);
18 //var_dump($head);
19 if($head != '') {
20 $a = unpack("ncmd/nlen", $head);
21 $cmd = $a['cmd'];
22 $len = $a['len'];
23 if($cmd == 8001) {
24 socket_recv($s, $body, $len, 0);
25 //echo $body;exit;
26 $b = json_decode($body, true);
27 socket_close($s);
28 return $b;
29 }
30 }
31 socket_close($s);
32 } catch(Exception $e) {
33 echo $e->getMessage();
34 }
35 }
36 $temp = insert_queue(8001, "insert into (num) values (%d)");

8 import Epoll
9 from Config import Config
10 from App.Queue.CircularQueue import CircularQueue
11
12 #获取队列服务配置
13 _config = Config("Queue")
14
15 #初始参数
16 _port = _config.get("queue.port") #服务端口
17 _app = CircularQueue()
18 #_allow_ip = ['192.168.1.100'] #白名单IP列表
19
20 #开始服务
21 s = Epoll.createServer(_app)
22 #s.setAllowIp(_allow_ip)
23 s.listen(_port)
24
25 启动服务
26 python3 circularQueue.py
测试工具
使用webbench模拟1万并发
webbench -c 10000 -t 30 http://192.168.1.100/client.php
测试结果
lxy@lenovo-pc:~$ webbench -c 10000 -t 30 http://192.168.1.100/client.php
Webbench - Simple Web Benchmark 1.5

Benchmarking: GET http://192.168.1.100/client.php
10000 clients, running 30 sec.
Speed=43226 pages/min, 129975 bytes/sec.
Requests: 21613 susceed, 0 failed.
每分钟相应请求数43226 pages/min，每秒钟传输数据量129975 bytes/sec
相当于每天可以处理（43226 * 60 * 24 = 62245440）个请求
这是小弟完成的第一个服务框架，写的不是很好，请大家多提意见，多批评
