  1. 🤩 New in Google Chrome Version 135 (Canary)

    Now, we can calibrate our computer to emulate low-tier and mid-tier mobile phones in CPU throttling.

    This great feature helps us improve the web performance by emulating more accurately.

    Thank you, Chrome DevTools Team 🥰

  2. Avoid marking too many requests as high priority - "If all resources are a priority, none is a priority"

    Selectively use the fetchpriority="high" attribute to prioritize only the most important resources, for example, the LCP image.

    Marking too many requests as a high priority could mean important resources could be delayed, for example, requests that block rendering

  8. The best way to improve web performance is with a data-driven approach.

    The most effective tool is Real User Monitoring (RUM), and if the tool has the target attribution, it becomes a great source of information to detect bottlenecks in the interactions that users make, especially in the new metric Interaction to Next Paint (INP).

    And @debugbear has this great feature 😊
