When enhanced tracking protection is on (android devices) it is very slow loading pages. With it off is quicker.

@acreskeyMoz Would it be low effort to measure the performance difference using our page load test frameworks?

We looked at them during Joy of Profiling but didn't see a clear cause. The suggested next steps are:

  • if you can reproduce, capture a new profile with all of the threads from the parent process selected (I'll try to get one)
  • (because we saw "After DNS request" takes longer in the ETP profile) read the code that takes these "After DNS request" timings and identify what the code is doing to find a cause for the long times
