In my programs if a physical core performs 1000 operations/sec, with an added HT core it performs 1070 ops/ second, not 2000 as I naively expected. I understand you should specifically program so that the main core performs integer arithmetics, and the HT core - floating point arithmetics, to get closer to 2000.
