php请求超时过高导致系统负载高的优化方法？

【描述】
request_slowlog_timeout = 1s   此值为超过一秒的php则记录到slow.log中
request_terminate_timeout = 30s 将执行时间太长的进程直接终止，不建议太长，易造成php程序僵死

◆ 操作方法
cd /opt/php5/etc/
将请求超时的时间改小点就可以了。
vi php-fpm.conf
cript execution for some reason
                        "0s" means "off"
                        <value name="request_terminate_timeout">60s</value>

                        The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
                        "0s" means "off"
                        <value name="request_slowlog_timeout">1s</value>
