Hello,

I can't desactivate the CPU throttling. It displays "4x slowdown (DevTools)".

Environment Information

• Affected Channels:
• Lighthouse version: Lighthouse 5.7.0
• Chrome version: 80.0.3987.106
• Node.js version:
• Operating System: Windows

Thanks for filing @jaouher2! That's because Lighthouse doesn't let you and only matches the throttling settings of PageSpeed Insights in DevTools :)

If you'd like to use custom throttling settings, use Lighthouse from the command-line with the advanced throttling options.

Hello,
Thank you for your reply.

I want to test a public website (visitors use desktop device only).
Can you advise me please which throttling configuration I should apply in my situation?

Thank you

Wait, if you're just measuring desktop then there's no CPU throttling to be deactivated in the first place. Update to a version of Chrome that has Lighthouse 6.x and you're good to go 👍 (Latest stable Chrome 85 has this)

OK, Thanks a lot 👍
