If you're like me, a slow-loading website can feel like medieval torture. Yes, I still remember the days of dial-up, but we should be past that by now. If your site doesn't load quickly, then I'm moving on.

In fact, USA Today reports that slow load times can account for big monetary loses. 

"Hotel giant Marriott, which Compuware Gomez ranks as the top-performing hotel booking site, believes it could lose nearly US$800,000 every hour its website isn't running, says George Corbin, the company's vice president of e-commerce strategy," Gary Stoller wrote for the paper.  

And when it comes to shopping online, customers expect websites to load in two seconds or less, with 40 percent saying they'll leave a page that takes longer than three seconds to appear. 

According to Compuware Gomez's study, Hotels.com has the fastest website for customer transactions, and Frontier Airlines has the slowest. 

"It took an average of four seconds for the Hotels.com website to complete the steps before a customer finalizes a booking, and more than 35 seconds for Frontier's website to do that for a ticket purchase," Stoller wrote. "Those times exclude the time a consumer spends looking at a website and typing in information."
