We all know that the performance of an UI is crucial for a nice customer experience. But what exactly do we mean when we talk about performance and "fast" websites? It's crucial to be explicit and refer to it in line with the desired criteria that can be quantified objectively. These criteria are usually referred to as metrics.
We structure the metrics around a few important questions to ensure that they are meaningful to users:
- Is the navigation working properly? Is the server still responsive?
- Is there enough material rendered for consumers to interact with?
- Is it possible for people to engage with the page, or is there too much traffic?
- Is the interaction fluid and natural, with no lag?
