Does Your Browser Affect Speed Tests?

Different browsers can produce slightly different results due to engine differences and extensions.

Why results differ

  • Extensions can block or slow requests.
  • Different JavaScript engines handle workers differently.

Best practice

  • Test in a clean browser profile.
  • Disable VPNs and heavy extensions.

What matters most

  • Consistency across tests is more important than small differences.
