Changing things "one at a time" is often the slowest way to do it... a
binary search is far faster, especially if the number of layers or
components involved is large.

Asuming you have 8 configuration or code changes to try, give them all
an identity number, test a group of 1#-#4, then #3-#4, then just #3 in
isolation.

I'm shocked how many technical people forget good old binary search
when not writing code...
