What is LCP by device CPU cores
LCP by device CPU cores shows the Largest Contentful Paint (LCP) value across different device CPU cores (e.g. 8 cores, 4 cores). This lens helps you identify which device CPU cores deliver a slower experience for your users.
The list shows only device CPU cores that generated traffic to your website during the selected period.
Common reason for slower LCP on certain device CPU cores is differences in hardware. Less capable hardware can affect LCP timing.
LCP is the most popular vital from the Core Web Vitals and represents the loading time of the largest element on the page.
Healthy LCP by device CPU cores sample
Should you worry
A healthy LCP by device CPU cores lens looks all green. Some device CPU cores may be greener than others, but as long as there's no yellow or red, it’s considered healthy. The greener the device CPU cores, the better.
Unhealthy LCP by device CPU cores sample
In the example below, LCP by device CPU cores shows that devices with 4 cores are both most popular and producing bad LCP. This often leads to a higher bounce rate, more exits, and lower conversion rates.
Resolving unhealthy LCP by device CPU cores
Go-to action plan to resolve an unhealthy LCP by device CPU cores:
Ask Uxi to analyze your LCP by device CPU cores values and suggest improvements.
Use Filters to focus on the slow device CPU cores in your LCP by device CPU cores then look across the other LCP lenses to find which ones show the slowest LCPs with the most pageviews.
Simulate LCP of the suspected lens to see if fixing it will resolve the slow LCP by device CPU cores. If yes, this is where the resolution focus should be.
Use an automated LCP optimization tool like Navigation AI to improve your LCP by device CPU cores values.
Once you’ve improved LCP, set an alert to be the first to know if it starts worsening again.
