今天用 ab 工具测试了一下框架，高效的性能让我吃惊

首先展示一下其他主要框架的测试：

测试用例是仓库中app/admin应用

我的测试环境：

与上面用 apache web 服务器不同，我用的是 nginx

php 版本： 5.6.0

php 扩展情况：

[PHP Modules]
Core
date
ereg
mysqli
mysqlnd
pcre
PDO
pdo_mysql
Reflection
session
SPL
standard
Zend OPcache

[Zend Modules]
Zend OPcache

php-fpm 配置：

pm.max_children = 8
pm.start_servers = 4
pm.max_spare_servers = 4
pm.min_spare_servers = 2

测试命令：

ab -n 10000 -c 4 http://127.0.0.1/account/signup

业务：

1. 构造和输出了一个 HTML 表单
2. 查询了一个 MySQL 空表
3. 初始化了 session, session 存在了数据库的一个 memory 表中
4. 路由用的是 symfony 的路由器

测试结果：

内存占用：

1. usage 2.4M
2. peak 2.4M

PHP 7.0 测试情况

opcache 版本：

Concurrency Level:      8
Time taken for tests:   7.578 seconds
Complete requests:      10000
Failed requests:        7
   (Connect: 0, Receive: 0, Length: 7, Exceptions: 0)

Time per request:       0.758 [ms] (mean, across all concurrent requests)
Transfer rate:          13199.60 [Kbytes/sec] received

无 opcache 版本：

Concurrency Level:      100
Time taken for tests:   190.636 seconds
Complete requests:      50000
Failed requests:        41
   (Connect: 0, Receive: 0, Length: 41, Exceptions: 0)
Total transferred:      512146699 bytes
HTML transferred:       500896699 bytes
Requests per second:    262.28 [#/sec] (mean)
Time per request:       381.271 [ms] (mean)
Time per request:       3.813 [ms] (mean, across all concurrent requests)
Transfer rate:          2623.55 [Kbytes/sec] received

有无 opcache 相差好大
