@rexi88 Thanks for sharing your considerations about FastCGI and W3TC.
I've managed to get a very high performance for a WooCommerce/WordPress powered website created with EasyEngine --wpfc (fastcgi_cache) + W3TC plugin installed/enabled, at least on the front-end.
On a 2GB SSD Digitalocean's droplet, running the --wpfc (fastcgi_cache) alone makes WordPress backend blazingly fast, however, when W3TC is enabled the backend gets terribly slow.
I have no experience with REDIS, I'll read more about it, but it seems to be worth it to give it a try with FastCGI.
Could you please point me out where I can find the REDIS recommended plugin? Does EE offer such set up as a creation command?
