Uso de memória alta do PHP-FPM

2

Eu tenho um blog wordpress, que usa o WP-SuperCache, e normalmente recebo 100 visitantes por dia. Com nginx + php-fpm é muito rápido, e não tenho arrependimentos.

Uma coisa que eu notei é que o php-fpm tem muita memória:

Aqui está minha configuração do php-fpm:

[global]

pid = run/php-fpm.pid
error_log = log/php-fpm.log
log_level = notice

[www]

listen = 127.0.0.1:9000

user = www-data
group = www-data

pm = dynamic

pm.max_children = 50
pm.start_servers = 3
pm.min_spare_servers = 3
pm.max_spare_servers = 10
pm.max_requests = 500

Às vezes, chega a 400MB. E estou planejando adicionar um novo site no meu VPS. Isso é normal?
