I'm using Nginx + PHP5-FPM and all PHP files loaded over port 80 are extremely slow - they take several minutes to load, even a simple phpinfo file.
php -i over shell is lightning quick, and the server itself is pretty powerful and has a very low load.
I've also tried Apache and Litespeed with the same results as Nginx. Flat HTML fiLes are also very quick.
This has been happening since a power outage and a hard reboot.
Has anyone got any ideas why this server could be so slow at processing PHP files?
