After many iterations, I finally went live with our real estate website:
Server: VPS running Ubuntu, MariaDB, nginx, PHP7, LetsEncrypt SSL(free btw) all setup via easyengine
Template: Yootheme Pro
Plugins: ACF, Facetwp, Widgetkit(just to get missing UIKIT3 functionality), W3TC, Sucuri, Timber Twig, Pods, Relevanssi, and more
Please keep in mind that because of the nature of real estate, the listing pages are on the rather large side in terms of page size due to the number of images you have to include. I did my best to fully optimize the image sizing to minimize resizing in html. I am currently not using a CDN so that kind of hurts my GTmetrix score, but I am pretty happy with the results. Personally I think it turned out pretty dang fast for what it does.
Please take a look and let me know what you think.
