PHP框架性能测试报告
作为一个PHP开发者，而且是初创企业团队的技术开发者，选择开发框架是个很艰难的事情。
用ThinkPHP的话，招聘一个刚从培训机构出来的开发者就可以上手了，但是性能和后期代码解耦是个让人头疼的事情。不过很多第三方功能不需要自己写，众多大牛已经给铺好路了。
用Laravel的话，传说写起来很爽扩展性也够，但是学习成本有点高，总不能给初级开发者半个月的时间去学习框架吧。而且据说江湖人士透漏，Laravel性能不怎么样，文档也并不是特别丰富。
用Yii的话，语法有点啰嗦，前后端代码分离有点小麻烦，不过性能是非常好的，而且已经有众多国内大公司在使用了，出现意外可以快速的找到大牛答疑解惑。
不如做个简单的性能评测，选个性能出色的总不会出错
性能测试
测试时间： 2016年05月06日
测试工具： siege (因为MAC系统的ab总是会出现 pr_socket_recv: Connection reset by peer (54) 的错误，所以选择了siege)
测试机器： MacPro Core i5 处理器/8GB内存/256GB SSD闪存
测试环境： Apache PHP5.6
框架版本： ThinkPHP 3.2.3 Laravel 5.2 Yii2.0.5
测试原则： 每次测试循环5次，取中等数据
补充说明：所有项目都是让在子目录中

开始测试
增加一个控制器，并在控制器中输入10000次HelloWorld
并发50循环10次：
首先向我们走来的是ThinkPHP，看上去还行

- Data transferred: 52.45 MB
- Response time: 0.46 secs

- Concurrency: 47.65
- Successful transactions: 500
- Failed transactions: 0
- Longest transaction: 0.88
- Shortest transaction: 0.04
并发200循环10次：
首先是ThinkPHP
- Transactions: 1977 hits
- Availability: 98.85 %
- Elapsed time: 10.03 secs
- Data transferred: 207.40 MB
- Response time: 0.95 secs
- Transaction rate: 197.11 trans/sec
- Throughput: 20.68 MB/sec
- Concurrency: 187.68
- Successful transactions: 1977
- Failed transactions: 23
- Longest transaction: 1.22
- Shortest transaction: 0.02
然后是Laravel
- Transactions: 1890 hits
- Availability: 94.50 %
- Elapsed time: 51.85 secs
- Data transferred: 198.27 MB
- Response time: 4.88 secs
- Transaction rate: 36.45 trans/sec

- Concurrency: 188.57
- Successful transactions: 1996
- Failed transactions: 4
- Longest transaction: 3.29
- Shortest transaction: 0.10
没想到在没有优化的情况下，ThinkPHP的速度是最快的，Yii略微多一些，Laravel步履蹒跚的跑完了测试。结果是有些出人意料的，不过上述的测试只代表了开发环境，下面会对框架进行优化，模拟线上环境。
优化框架
ThinkPHP：
APP_DEBUG改为false
Laravel：
- APP_DEBUG改为false
- php artisan route:cache
- php artisan optimize
- php artisan config:cache
- composer dumpautoload -o
Yii：
YII_DEBUG改为false
composer dumpautoload -o
并发200循环10次：
ThinkPHP
- Transactions: 1655 hits
- Availability: 82.75 %
- Elapsed time: 8.21 secs
- Data transferred: 173.62 MB
- Response time: 0.69 secs
- Transaction rate: 201.58 trans/sec
- Throughput: 21.15 MB/sec
- Concurrency: 139.29
- Successful transactions: 1655
- Failed transactions: 345
- Longest transaction: 7.83
- Shortest transaction: 0.00
Laravel:
- Transactions: 1520 hits
- Availability: 76.00 %
- Elapsed time: 34.95 secs
- Data transferred: 159.45 MB
- Response time: 3.15 secs

- Shortest transaction: 0.00
Yii:

- Availability: 85.20 %
- Elapsed time: 15.16 secs
- Data transferred: 178.76 MB
- Response time: 1.46 secs
- Transaction rate: 112.40 trans/sec

- Concurrency: 164.21
- Successful transactions: 1704
- Failed transactions: 296

比较奇怪的一点，当框架关掉调试模式后都出现了较多失败的情况。不过明显的看到，Laravel进行简单的优化后，性能大大的提升了，但还是低于其他两个框架。
结论
在测试的过程中，其他我的心情是沮丧的，感觉自己的三观世界已经崩塌了，崩塌至渣。
ThinkPHP的性能比Yii高出一倍，比Laravel高出近四倍
Yii的性能比较中庸，但是在测试中会明显发现请求失败的情况比其他两个框架要少
Laravel依旧优雅，不过性能堪忧，用网友的话形容比较好 学之者生用之者死
最后
我的项目最后使用了自建框架进行开发，得益于composer的强大，开发的过程非常顺利，最后附上自有框架在200并发10次循环的数据，框架开源但是更新比较忙，欢迎在github上搜索PPPHP，和我一起搭建框架。
