Los procesos del grupo php-fpm ocupan 250 MB cada uno

Mi servidor centos 6.7 tiene solo mis sitios web de bajo tráfico basados ​​en php y mysql (un total de alrededor de 3000 páginas vistas por día para todos los sitios web) que utilizan el servidor web nginx y virtualmin (sin wordpress ni scripts/software externos).

Instalé PHP con:

yum --enablerepo=remi,remi-php56 install -y php-mysqlnd php-gd php-fpm

yum instaló dependencias como php-commom, php-pdo, etc.

Revisé los procesos en ejecución en mi servidor usando virtualmin.

Inmediatamente después de reiniciar php-fpm, cada php-fpm: pool wwwEl proceso está utilizando alrededor400MBmemoria.

Hay más de 20 extensiones en el directorio etc/php.d.

Comenté la mayoría de las extensiones en el directorio etc/php.d.

después de reiniciar php-fpm y nginx,

Revisé las extensiones instaladas usando

<?php
print_r(get_loaded_extensions());
?>

Este es el resultado :

[0] => Core
[1] => date
[2] => ereg
[3] => libxml
[4] => openssl
[5] => pcre
