php hhvm nginx并发,php – HHVM fastcgi Nginx性能波动
目前,我们已开始在生产环境中使用HHVM,到目前为止,几乎所有结果都非常令人反感.与使用APC的PHP-FPM相比,我们的整体交易率大大提高.几乎所有请求都在500毫秒以下,但是每隔几个请求(5到10个左右)就会产生2到5秒的请求时间.
请求的页面似乎没有任何区别,并且一遍又一遍地请求同一页面将在几个请求中触发此行为.
我们使用以下命令行选项在服务器模式下运行HHVM：
/usr/bin/hhvm --mode server -vServer.Type=fastcgi -vServer.FileSocket=/usr/local/PHP55/sockets/admin.sock -vPidFile=/var/run/hhvm/admin.pid -vEval.Jit=true -vServer.ThreadCount=24 -vServer.APC.EnableApc=true
我们正在为这些相关配置的网络服务器运行Nginx(对不起,如果我忘记了一些重要的东西).
fastcgi_buffer_size 128k;
fastcgi_buffers 256 16k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_read_timeout 240;
fastcgi_intercept_errors on;
服务器有128GB内存和24个内核(超线程实际上是12个).
我们在https://github.com/facebook/hhvm/wiki/Runtime-options上进行了相当多的搜索,但大多数选项都没有得到很好的解释,所以我不知道他们做了什么,在生产环境中测试它们有点可怕.
如果这里的任何人有类似的问题,或者可能指出我的方向与一些HHVM选项我会非常感激.

我们正在使用supervisord启动HHVM,所以这里的主管配置如下：
[program:hhvm]
stopasgroup=true
killasgroup=true
command=/usr/bin/hhvm --mode server -vServer.Type=fastcgi -vServer.FileSocket=/usr/local/PHP55/sockets/admin.sock -vPidFile=/var/run/hhvm/admin.pid -vEval.Jit=true -vServer.ThreadCount=24 -vServer.APC.EnableApc=true
user=admin
stdout_logfile=/var/log/hhvm/admin.log
stderr_logfile=/var/log/hhvm/admin.error.log
directory=/home/admin

/etc/hhvm/PHP.ini中有一个PHP.ini,但内容为空.所有页面都尝试了一些数据库连接,但这通常是非常小的.完整的图片也是my.cnf.使用的MysqL版本是percona
