似乎PHP-fpm正在分配越来越多的内存,尽管请求数量达到峰值和下降.
无法发布多个图片,所以我把它们放到了 here.
正如你在uri的图片中看到的那样,一张图片Nginx请求,显示明显的下降和峰值.
其他的,每个孩子的PHP-fpm内存和平均内存似乎都没有遵循相同的模式.只有重启PHP-fpm才会产生效果,即便如此,我也不能说我发现性能有任何变化.
系统很好,响应时间很好,一切都很好,只是好奇这是否是预期的行为,是否有性能优势或应该避免(通过降低max_requests或其他东西？).

系统正在运行Debian GNU / Linux 6.0 Squeeze,AMD64. PHP版本5.3.6.
PHP 5.3.6

pool.d / www.conf：

pm.max_children = 50
pm.start_servers = 30
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 1024

我已经在PHP-fpm.log中获得了这些,因为它是刚刚安装的：
