Moved logo-centos-7distro again because I somehow managed to break MariaDB on Ubuntu.. So instead I’m back to Percona on CentOS, which I upgraded to v7 now. CentOS 7 WordPress with Percona and Redis! Mind you I am not running HHVM anymore so the site will be slower. Turns out there’s a memory leak when it comes to Crayon, the syntax highlighting plugin I use. I have to look for a nice caching solution, preferably using Redis..

UPDATE: Found my redis solution! https://github.com/BenjaminAdams/wp-redis-cache
Without being logged in the blog loads in 13ms now, that’s even faster than varnish 🙂

UPDATE: Turns out I was overloading my VPS and the dreaded OOM killer struck and killed Percona. So I’ve upgraded to a 2GB VPS and I’ve added DataDog monitoring to Nginx, Percona and Redis just to see what’s going on. Here’s an example of my dashboard at DataDog. It’s a bit of a build it yourself NewRelic and free up to 5 hosts!
