I do know AE does not always handle lots of threads well - but is Adobe
saying it's HTT to blame or overall MP management. AE should not care - the
OS and CPU should try to handle it.

I'm not a programmer but I know MP can't work with Raytracer, many
time-based plugins. Is this related to HTT performance - AE is making calls
somehow to the physical cores that can't be processed? Or asking for CPU
resources that cannot be split across the virtual cores (which supposedly it
cannot identify)?

Any suggestions on a test to properly figure this out? I see performance
improvement on renders with HTT turned on - but not every time and with
every project. And like Greg B. - the information out about HTT on AE is not
in agreement with what Chris M. and Steve F. are posting now.

A film is - or should be - more like music than like fiction. It should be a
progression of moods and feelings. The theme, what's behind the emotion, the
meaning, all that comes later.

This is just confusing the heck out of me, because I'm pretty sure I
understood it all until today. 

I most certainly see a big difference rendering in AE with MP turned on and
Hyperthreading enabled. AE has no clue the difference between a 4 core
system with HT on or an 8 core with no HT. 

As long as I have the ram to power the "virtual" cores, AE doesn't care if
they are virtual cores or not. 

They are two different things, but AE's Multiprocessing most certainly takes
advantage of all threads available to it.
