Comment (by galapogos01):

 I have and I am.

 Through some profiling I managed to narrow down the issue to the popular
 Enfold theme. It had an issue with textdomain initialisation that only
 showed up where a translation was missing, which happened to be in my case
 (en_AU). Subbing in a translation file, or their hotfix (documented at
 https://kriesi.at/support/topic/wp-6-1-enfold-performance-
 issue/#post-1404110 ) bought page load times down ~3x.

 Even after this fix I am finding the theme is measurably slower on 6.1+
 than it is on 6.0.1. I was expecting page load improvements - still very
 unsure about taking this into Production.

 Cheers, Jason
