But do you know how Lighthouse calculates performance metrics like First Contentful Paint (FCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS)? Still, there’s nothing in there to tell us about the data Lighthouse is using to evaluate metrics. But it comes with caveats. So why use lab data at all?

Database uptime and availability Monitoring database uptime and availability is crucial as it directly impacts the availability of critical data and the performance of applications or websites that rely on the MySQL database. That said, it should also be monitored for usage, which will exhibit the traffic pressuring them.

The primary challenge being not able to access the underlying infrastructure metrics. However, when the time comes for resources to be requested, there can be latency in the time it takes to for that code to start back up. Applications that are running continuously on a dedicated server aren’t as impacted by latency issues.

SLIs are the actual performance metrics of your services. For example, if your SLO states that your uptime must be 99.9%, the actual SLI must meet or exceed that performance metric in order meet that specific SLO. An agreement within the SLA that states specific metric, like uptime, response time, security, issue resolution, etc.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

Websites would magically become 50% faster with the flip of a switch!
