Piwigo with php-fpm for better performance

Hi,
I was wondering if manage to get this issue solved of high CPU and Memory usage?
I have just install piwigo (latest) on my DS916+ (8GB RAM) and everything is working okay, but the CPU and Memory usage is constantly high when browsing through the photos via web-interface of mobile apps.

If someone has a suggestion or a fix please don’t be shay :wink:
