From a development standpoint (easy to setup and customize) and ease of use for the client (update abd maintain) what is the best CMS and shopping cart combination? Or is there a shopping cart application that can be used as a CMS (or vice-versa) ?
My experience with WordPress is that it runs decent for blogs and small sites but it runs painfully slow with larger sites - so I prefer to avoid it.
I am hoping for objective suggestions from someone who has first hand experience with building and maintaining e-commerce websites.
Thank you in advance for your advice.
