I'm reading my reports from firebase web performance and I don't understand what means the percentage value in the distribution graph.
Bellow a print of the loadEventEnd with the graph.
Is the value 95% represents users affected with the load time of 11.85s?
Thanks
What you're seeing there is the 95th Percentile number. That means that if you ordered all events from fastest to slowest, five percent of all requests took 11.85s or longer.
Percentile metrics are very useful for measuring performance problems in the margins -- your median load time may be great, but if 5% of users are experiencing a very long load time, it might be worth trying to dig into why and optimizing it more.
A great exercise might be to use the filters that are available to try to find a cohort of users for whom the median number is closer to that 95p number -- for instance, a specific browser or geographical region. That will give you more insight into who exactly is having a slower experience on your site.
