I've come from vpssim running xenforo with nginx, front end caching, back end memcached and opcache on the php files. It was quite well optimised, but now I need to change that to run under Centmin. I've noticed a few posts on caching and optimisation of XF, with Centmin but they are a little older. Whats the best optimisation now? I need it to work well as my servers are US, and the community is NZ based. Thanks also for the XF2 install - I can't belive how simple you made the whole process for me to follow.
