This includes metrics such as query execution time, the number of queries executed per second, and the utilization of query cache and adaptive hash index. That said, CPU or memory usage is not only limited to these two variable configurations, and further analysis is required to track what’s causing the usage spikes.

This reduction in latency ensures that applications and websites provide a more rapid and responsive user experience. Query plan analysis can also provide valuable insights. Key metrics such as CPU usage, memory usage, and disk I/O offer insights into how efficiently your database server operates.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Quantitative performance testing looks at metrics like response time while qualitative testing is concerned with scalability, stability, and interoperability.

This PoC demonstrates how to install and configure pg_stat_monitor in order to extract useful and actionable metrics from a PostgreSQL database and display them on a Grafana dashboard. This simplifies debugging and analysis processes by enabling users to execute the same query. About the environment Grafana: version 10.0.0

With a staff of slightly over 175 full-time employees (less than 1/2 in consulting roles), we must therefore focus on highly-leveraged performance analysis projects, rather than labor-intensive ones. Bounds on overlap are discussed near the end of the presentation, in the slides titled “Analysis” The approach is opportunistic.

The scale of the effect can be deeply situational or hard to suss out without solid metrics. Since then, the metrics conversation has moved forward significantly, culminating in Core Web Vitals , reported via the Chrome User Experience Report to reflect the real-world experiences of users. Today, either method returns a similar answer.

Budgets are scaled to a benchmark network & device. This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. Very rarely have we seen a team succeed that doesn’t set budgets, gather RUM metrics, and carry representative customer devices.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. Another window into this question is provided by the Web Confluence Metrics project.
