HHVM手动编译太不友好了，如果你本身的环境不是纯净的环境，用过yum安装过其中的一些必须要求的库的话，就不要手动编译了，各种报错让你感动。自行编译一些库的话，也有坑，一些库的版本不能低也不能高，要求实在太多了，排了两天错才搞定编译。所以强烈建议少折腾，直接用官方提供的预编译包！！！

不过还是挺令我欣喜的
简单benchmark一下,同样跑一个Typecho的话

下面是HHVM+Nginx的结果

测试期间，CPU占用大致相当，同样的时间HHVM几乎完成了两倍的请求
Nice!

这跑的什么程序啊，qps 37，是各种计算么

估计不用Nginx的话性能会更高点...

varnish应该会更棒。。。phpng也不错，hhvm太吃内存了

CentOS 5.1，无缘HHVM了。
只能下次迁VPS的时候再换上了。

感觉 HHVM 官网的测试有些水分，之前我测过 yii 框架下简单的 controller/action，带一次memcache 请求。

其中 nginx + php-fpm(5.4)，开 APC 扩展，单机 QPS 2.2w 左右，性能瓶颈只在网卡。
HHVM，单机 QPS 也在 2.2w 左右，比 php-fpm 略高，也是性能在网卡。

另外看过一个老外的 blog，也是说 HHVM 没那么绚丽，测试得到的数据和我差不多。而且他测的 php5.6 QPS 甚至比 HHVM 高。

印象中 HHVM 只对计算类有用，官网的测试数据都是各种计算类的。但实际开发中通常不会把复杂计算放到请求处理中，都是业务逻辑外加数据库、redis 等各种操作，HHVM 的优点似乎发挥不出来。
