Is it possible that my site is running slow and that's why people are giving up on the cart page?

I've been noticing something weird with my Shopify store lately. Our traffic looks solid—we're getting decent visitors through our Meta ads—but something's happening on the cart page that's killing our conversions. I've watched our analytics, and the cart abandonment rate is frustratingly high. At first, I thought it was just normal e-commerce behavior, but then I started timing how long our pages take to load. Let me tell you, it was painful. Each click feels like an eternity, and if I'm experiencing this drag, imagine what potential customers must feel. We're talking about milliseconds that could be costing us serious revenue. In a world where consumers have zero patience, a slow-loading cart page isn't just an inconvenience—it's a conversion killer. I'm seeing visitors add products, get to the cart, and then... nothing. They just disappear. The potential lost sales are keeping me up at night. Is my site's performance sabotaging all the hard work we're doing in marketing? I need a solution that can diagnose these performance issues and help me understand exactly what's happening in those critical moments when a potential customer decides to bounce.
