Do I Choose WooCommerce or WordPress?
It’s a good thing that you asked! If you have a WooCommerce store, you should directly create a server with WordPress with WooCommerce installation. This way, you will get the full benefit of Varnish cache on your WooCommerce store through the W3TC plugin.
If you install and activate the WooCommerce plugin on your current or new WordPress installation, you will end up with a WooCommerce store without Varnish cache. Without this crucial component, your store will not be able to handle simultaneous visitors efficiently.
Without Varnish, the average response time is a whopping 1779 ms.
With Varnish, the response time is a steady 6 ms.
