Thanks for the info also.
Ok other than using a CDN what would be the next step in increasing performance. Mainly TTFB.
Would having another server for the database help with this?
I am quite happy with my setup however want to learn more and dig a little deeper.
Also has anyone had experience using a separate caching server sitting in front such as Varnish or NGINX FastCGI-cache. How does something like that compare to a REDIS setup on the same server?
Yeah I thought be providing my images from another server would help increase page load not so much TTFB. I will look into cloudflare and others as well. But I do want to play with server stuff a little more before adding the CDN in. As my site is only targeting 1 country.
