If you use PageSpeed Insights, that’s Google’s own tool and the same one they use to evaluate and rank websites in terms of performance and Core Web Vitals.Koons was originally on DealerOn, and I've never seen one of their sites take 26 seconds to load.
That stat comes from a 3G mobile test, which isn't really representative of a typical user experience.
And based on what I’ve seen, most dealership websites don’t come close to meeting Google’s recommended thresholds. Whether it’s desktop or mobile (3G or not), failing those benchmarks can impact rankings and user experience.
It’s not just about how fast a site “feels”, it’s about how well it performs under the conditions Google actually tests for.
Google intentionally uses simulated slower connections (like 3G) in their Lighthouse/PageSpeed Insights tool because it reflects worst-case scenarios and helps developers optimize for performance across all users, including those with slower devices, older phones, or spotty connections.
Even if your typical user is on 5G or high-speed Wi-Fi, Google’s Core Web Vitals are scored based on that simulated 3G mobile environment — because:
- It highlights inefficiencies
- It ensures a broad, inclusive user experience
- It helps prevent performance cliffs for users in less-than-ideal conditions
