I am hosting a wordpress site on a 512Mb digitalocean VPS. All is good, varnish is getting a perfect hit rate. Logged in users bypass.
The only thing i am noticing is php5-fpm is firing every visit.
How can i track down what is managing to bypass the cache and pass on to the backend.
The system load is drastically better and varnish is amazing for such a small VPS but its my goal to find out why php5-fpm is firing when i dont think it is needed.
