Why do we need Lighthouse at all when Google also offers similar reports in PageSpeed Insights (PSI)? The truth is that the two tools were fairly distinct until PSI was updated in 2018 to use Lighthouse reporting. Google focuses on the 75th percentile of users in the CrUX data when reporting core web vitals metrics.

Google recommends that TTFB be 800ms at the 75th percentile. Charlie Vazac introduced server timing in a Performance Calendar post circa 2018. Latency – How much time does it take to deliver a packet from A to B. For more years than I care to mention, I've been advising folks that their TTFB should be under 500ms.

While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user.

India became a 4G-centric market sometime in 2018. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. CrUX data collection and first-party RUM analytics of these metrics require live traffic, meaning results can be predicted but only verified once deployed.

This post was originally published in July 2018 and was updated in July 2023. It efficiently manages read and write operations, optimizes data access, and minimizes contention, resulting in high throughput and low latency to ensure that applications perform at their best. What are the differences between Aurora and RDS?
