1. General question about synthetic performance monitoring:

    How do you define the device/network settings of your tests?

    • Do you use low end devices / bad network to easily detect issues?
    • Or do you try to be close to your RUM data, to have more predictability when you deploy changes?

    I usualy do the former, but I think both could be useful.

  2. Do you know good tutorials and/or examples about dealing with responsive images that are fluid horizontaly, but with a fixed height?

    Using object-fit: cover; in the CSS is easy, but how can we prevent loading many pixels that will be hidden, without using too many <source> in a <picture>?
