I'm not entirely sure.

If you have an example you can send me (which I'd treat confidentially),
I will investigate.

Just a FYI.. I've been playing with some complex 8 layer designs I got
from another PCB user, and I got a 200+ second load time down to 3
seconds now ;)

I added some more polygons on the unfinished layers, found a case which
pushed load time up to 50 seconds (lots of touching via clearances), so
futher profiling + patching, and the load time is now down to ~10
seconds for that more complex board).

Long story short.. send slow examples, and they might well get profiled
and used to help optimise PCB's speed for that kind of case.

Best wishes,
