Synthetic website performance tests measure page load time in a controlled lab environment with a specified network speed.

Since these tests are often run on a computer with a fast network connection, the network needs to be throttled to achieve a consistent result that reflects how visitors with a slower connection would experience the page.

However, there are different ways to throttle the network. This article explains why packet-level throttling is the most reliable option and how it’s different from network throttling in Chrome DevTools or the default settings in Google Lighthouse.

Web performance metrics always vary somewhat between tests. This variability will be lower for simple static sites, and higher for complex dynamic content that changes every time the page is loaded.

One way to reduce variability in recorded metrics is to run each test several times and only save the average result.

This article will look at three different websites and investigate how much running tests 1, 3, 5, or 7 times reduces variability.
