ab测试
装apache 的AB
1ubuntu安装AB：
`sudo apt-get install apache2-utils`
2.centos安装ab：
yum -y install httpd-tools
安装后就可以开始测试
1.硬件：阿里云机器，1核cpu，4g内存（上面有很多其他的网站应用，因此可以看成3G的内存）
2.php-fpm
pm = dynamic
pm.max_children = 20
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 20
3.阿里云上面还有其他的一些站点，另外还开了一个php5.4，因此资源虽然是4G，但是用于测试的可能3G内存都不到
4.用于测试的url
4.1:在controller部分直接返回数据的url
， http://fecshop.appfront.fancyecommerce.com/customer/test/test
public function actionTest(){
echo 12;exit;
}
这个相当于测试框架的性能，也就是框架初始化带来的时间消耗，用这个和fecmall添加逻辑后的时间消耗做对比
4.2:fecshop appfront部分的产品链接：http://fecshop.appfront.fancyecommerce.com/alluring-long-sleeve-open-back-draped-maxi-dress-55525232
5.以上测试是本地测试，没有网络开销
5.1在/etc/hosts中做了指向，http://fecshop.appfront.fancyecommerce.com 指向127.0.0.1,这样不会由网络开销
5.2Apache AB和fecmall，都是在同一台机器上面，Apache AB也会耗费一定的资源
测试1
php.ini没有开启opcache,fecshop没有开启缓存
1.测试一下初始化：http://fecshop.appfront.fancyecommerce.com/customer/test/test（这个url在controller中进行输出后，直接exit）

测试4 appserver这种api端
1.没有开启缓存

2.appserver 开启cache
开启cache： @appserver/config/fecshop_local_services/Cache.php
设置enable 为 true，如果没有这个文件，将@appfront/config/fecshop_local_services/Cache.php复制过去，然后设置enable 为 true
注意，更改文件要重启下php，因为开启了opcache

可以看到速度提升到了98.52 [#/sec]
,开启cache，访问产品分类，速度提升还是很明显的。
总结：
php7.1， 1核3G的内存下。
1.Yii2框架，在开启opcache后，有一个质的提升，大约10倍的速度提升
2.fecshop可以通过开启opcache 和 fecshop缓存，，达到100.00 [#/sec]的并发
3.对于自己开发的一些api，也尽量的加缓存，增强并发
4.如果是线上服务器压测，因为有网络开销，像阿里云还有流量的限制，因此需要走内网测试，可以通过hosts，将访问的域名映射到127.0.0.1，然后在本机进行ab测试，譬如我添加的
vim /etc/hosts
127.0.0.1 localhost xunsearch elasticsearch1 fecshop.appfront.fancyecommerce.com fecshop.appserver.fancyecommerce.com
访问 fecshop.appserver.fancyecommerce.com 直接走本机，不走外部网络。
5.本部分只对开启opcache 和 fecshop缓存 后的并发数进行测试，而且是1核3G内存进行的测试，如果您的机器内存高，cpu数量多，可以多开php-fpm, 并发数会更高
6.其他的更多的性能提速的文档，参看：http://www.fecshop.com/doc/fecshop-guide/instructions/cn-1.0/guide-fecshop_online_speed.html
