Of note it appears that disabling CMP on a model that has a CPU with Hyperthreading disables the threads you would expect to see from HT. So for a BIGIP 4000 that has a single quad-core CPU with HT, with CMP enabled you have 1 TMM instance with 8 threads- TMM0.1, TMM0.2...TMM0.7

 

With CMP disabled, we see only 4 threads available, 1 per core. Still unsure whether disabling CMP should limit the single TMM instance to one core (or thread)......
