If you don't mind me asking, why would you say ghash.io is the worst? OP says he's got roughly 1.14th/s and is only getting .09 per day with his pool and I have about 760 gh/s on ghash.io and i'm getting about the same per day.
I've mined several pools with S1 and ghash.io was the worst of them all by far in terms of mined bitcoins/day. The site displays the full GHash Speed, but the reward is as poor as OP's. Maybe it's an Antminer S1 specific problem or some special ghash.io option?
