我一直在尝试解决由 php-fpm 进程导致的 CPU 峰值问题。我已将 php-fpm 配置设置减少为：
pm = ondemand
pm.max_children = 12
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 10
pm.max_requests = 500
php_admin_value[memory_limit] = 128M
问题仍然存在。我正在运行一个 Joomla 主站点（没有问题）和一个子目录中的 Magento 商店。我的服务器是 Linux CentOS，运行 NGINX、APC、Memcached、全页缓存和 php-fpm。我的服务器有 8 个核心和 16GB 专用内存。我的主机在过去一周多次关闭我的服务器，因为我的 php-fpm 进程正在消耗整个网络。许多单独的 php-fpm 进程占用了超过 50% 的 CPU。我聘请了几位“专业人士”，但他们都无法帮助我，所以现在我破产了，不知所措，我向你们求助。所以任何建议都将不胜感激。我打开了慢速 php 日志，以下是一些最新结果：

_____________________________________________
我还注意到服务器没有使用太多内存：
Mem: 16777216k total, 1204040k used, 15573176k free
My.conf 设置：
query_cache_size = 128M
innodb_buffer_pool_size = 512M
open-files-limit = 8192
table_cache=4096
我刚刚注意到有人将我的 innodb_buffer_pool_size 更改为 512M。难道不应该将其设置为可用 RAM 的 80% 吗？所以我有 16GB RAM，所以应该设置为 12G；但是，我将其设置为 10G。你怎么看？我做了那个更改并重新启动了一切。php-fpm 仍然在占用大量 CPU。这里只有 1 个 php-fpm 进程：
23942 user 17 0 507m 99m 27m R 90.9%CPU 0.6 0:03.46 php-fpm
我确信你们可能需要更多信息来提供帮助，所以请告诉我你们需要什么来帮助我解决这个问题。谢谢。

您安装 munin 了吗？
你说的“消耗整个网络”是什么意思？你是说一台 magento 服务器上有那么多流量吗？
您平均和峰值有多少个 php req/s？
