주류 PHP 프레임워크 성능에 대한 비공인 테스트
PHP 개발자이자 스타트업 팀의 기술 개발자로서 개발 프레임워크를 선택하는 것은 매우 어려운 일입니다.
ThinkPHP를 사용하면 훈련기관을 갓 졸업한 개발자를 영입해서 시작할 수 있지만 성능과 포스트코드를 분리하는 것은 골치 아픈 일입니다. 그러나 많은 전문가들이 이미 길을 닦았으므로 많은 타사 기능을 직접 작성할 필요는 없습니다. 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 3.2.3Laravel 5.2Yii2.0.5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
结果说明
Transactions: 2119 hits 处理请求总数量 Availability: 96.85 % 可用性 Elapsed time: 9.74 secs 运行时间 Data transferred: 1.31 MB 数据传输量 Response time: 0.60 secs 响应时间 Transaction rate: 217.56 trans/sec 每秒处理效率 Throughput: 0.13 MB/sec 每秒处理数据 Concurrency: 130.28 并发 Successful transactions: 2162 成功的请求 Failed transactions: 69 失败的请求 Longest transaction: 2.85 最长的单个请求 Shortest transaction: 0.01 最短的单个请求
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
Transactions: 500 hits Availability: 100.00 % Elapsed time: 2.81 secs Data transferred: 52.45 MB Response time: 0.26 secs Transaction rate: 177.94 trans/sec Throughput: 18.67 MB/sec Concurrency: 47.10 Successful transactions: 500 Failed transactions: 0 Longest transaction: 0.48 Shortest transaction: 0.03
然后是Laravle，嗯，略微有些失望
Transactions: 500 hits Availability: 100.00 % Elapsed time: 13.33 secs Data transferred: 52.45 MB Response time: 1.27 secs Transaction rate: 37.51 trans/sec Throughput: 3.93 MB/sec Concurrency: 47.55 Successful transactions: 500 Failed transactions: 0 Longest transaction: 3.64 Shortest transaction: 0.07
最后赛前比较看好的Yii
Transactions: 500 hits Availability: 100.00 % Elapsed time: 4.84 secs Data transferred: 52.45 MB Response time: 0.46 secs Transaction rate: 103.31 trans/sec Throughput: 10.84 MB/sec 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 Throughput: 3.82 MB/sec Concurrency: 178.00 Successful transactions: 1890 Failed transactions: 110 Longest transaction: 26.01 Shortest transaction: 0.07
最后是Yii
Transactions: 1996 hits Availability: 99.80 % Elapsed time: 18.95 secs Data transferred: 209.39 MB Response time: 1.79 secs Transaction rate: 105.33 trans/sec Throughput: 11.05 MB/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 Transaction rate: 43.49 trans/sec Throughput: 4.56 MB/sec Concurrency: 136.84 Successful transactions: 1520 Failed transactions: 480 Longest transaction: 19.18 Shortest transaction: 0.00
Yii:
Transactions: 1704 hits Availability: 85.20 % Elapsed time: 15.16 secs Data transferred: 178.76 MB Response time: 1.46 secs Transaction rate: 112.40 trans/sec Throughput: 11.79 MB/sec Concurrency: 164.21 Successful transactions: 1704 Failed transactions: 296 Longest transaction: 9.04 Shortest transaction: 0.00
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Laravel을 사용하면 쓰기가 매우 편하고 확장성이 충분하다고 하는데, 후배 개발자들에게 반달의 학습 시간을 줄 수는 없는 수준입니다. 프레임워크. 그리고Laravel의 성능이 그다지 좋지 않고, 문서도 특별히 풍부하지 않다는 사실이 전 세계 사람들에게 공개되었다고 합니다.
Yii를 사용하면 문법도 좀 번거롭고 프론트엔드와 백엔드 코드 분리도 조금 번거롭지만 성능은 매우 좋아서 이미 사용하고 있는 부분입니다 국내의 많은 대기업에서는 사고가 나면 신속하게 큰 사고를 찾아내며 궁금증을 해결해줍니다. 간단한 성능 평가를 하는게 더 좋고, 성능이 뛰어난 것을 선택하면 틀릴 일이 없습니다
