production on dual HT xeon 's (running SMP linux)

Exactly, it works well and as designed for certain specific applications which is why it was designed in in the first place. HT works remarkably well for certain specific benchmarks.

HT certainly offers more advantage than disadvantage, hence why it is there. However, there are other design considerations surrounding how, why, and its usefulness.


Disclaimer: I favour the AMD designs on engineering merit. I am not connected with either Intel or AMD in any way.
