The Environment:
I had my Ghost Blog listening on port 2368 and exposing port 80 on Docker so that the port translation directs port 80 traffic to port 2368 on Ghost directly.
Alex responded on my tweet and introduced Nginx Caching:
With this approach benchmarking results was not so great in terms of requests per second, and as this hostname will be only used for a blog, its a great idea to cache the content, this was achieved with the help from Alex’s blog: blog.alexellis.io/save-and-boost-with-nginx/
How Nginx was Configured:
I have a blogpost on how I setup Nginx on an Alpine Image, where I setup caching and proxy-pass the connections through to my ghost blog.
Benchmarking: Before Nginx with Caching was Implemented:
When doing an apache benchmark I got 9.31 requests per second performing the test on my LAN:
