Then you are using a terribly inefficient and old CPU mining program. I get 3.9MH/s per core of my non-overclocked 1090t.
I have an 1090T too. That would be 23.4MH/s, which is something but I think isn't worth the power. GPU's are a lot more cost efficient. My Radeon 5750 gets 140MH/s with probably about the same power use as the 1090T would take. (That said, I haven't tried measuring actual power, and it's possible to undervolt the 1090T significantly.)
