Chrome 80 - Desktop throttling profile not using lr-desktop-config #10315

Description

@Rombecchi

Provide the steps to reproduce

  1. Run LH on http://www.ideacasaimmobiliare.it/web/ with this options flagged:
  • Performance
  • Best practices
  • Accessibility
  • SEO
  • Desktop
  • Clear storage
  • Simulated Throttling
  1. LH runs correctly but loading web site resources take very long time

What is the current behavior?

All the web site weights about 3 Mb but LH takes about 8.4 seconds for FMP and score 10.2s for speed index!

What is the expected behavior?

This is a very strange behaviour because in Italy, for desktop sites (DSL home line) a web site loads in about 2 secs!
Removing throttling and leaving clear cache flagged gave me same results.
I can't show my customers a report showing that a 3 Mb site loads in 10 seconds!

Take a look at the report
