Allow me to say one thing: this is exactly why we need a paid developer.
So we can get things like this solved. So we can keep our new features,
and get even more new ones, without each new feature causing
progressively worse performance.

Way ahead of you. You should look into oprofile - it can give pretty
good stats about which parts of the software most time is spent on. Not
sure if available on windows though.
I've only tried it on the memmgr branch so far, but one of the things
that stood out was the new FxMixer, particularly:
FxChannel::doProcessing(). So this was in memmgr branch, but I bet the
issue is common with stable-1.1 as the FxMixer doesn't have that much
difference there. So obviously there's still things that need optimizing
in the FxMixer.
