With my old P4
(single core) HT restricted my AI to 64/2
with the ocasional xrun, HT off would allow solid 16/2 performance. My
new i5 does not have HT, so I am not able to compare.
+1 for testing + measuring.
Anyway. In most cases the CPU is not the limiting factor. In the vast
majority of cases some power-saving (bus-freq, southbridge, SMI) or
weird graphics-cards, wifi, etc and/or their drivers are orders of
magnitude more limiting.

And then there's design efforts like the Liquorix project; and also
CPU-optimized kernels. I have recently been compiling CPU-optimized
versions of Liquorix kernels...yum :-)
