Thanks David. It was not my decision to use Hostgator. The account at Hostgator is their “Business Plan” which is low-cost shared hosting, but it’s the more expensive of the 3 low-cost shared hosting plans they offer.
If/when traffic increases, I can make a case to upgrade or move to a different host. At the moment, I’m mostly looking to be able to improve the score to show that efforts have been made and it meets a minimum standard for efficiency. Since loading times are somewhat subjective and subject to multiple variables (computer, connection, time of day, etc).
