What is "normal" (I mean currently achievable with tuning) hashrate for R9280X?

I see there are some miners with this card, but my setup performs just below 1 MH/s, way too slow in comparison with GTX 750Ti.
Any ideas? Do I really have absolutely badly tweaked miner, or the internals of the miner are not well optimised?

Regards,
Andy

I've tried many combinations of parameters with my 280X,1 MH/s is the stable speed.

I am testing an improved miner that goes up to 2Mh/s on my r9 280x, but as i said, i am still testing it, so i am not responsible for it not working or working incorrectly for it. If you want early access to it, the source is on github (no, i will not release binaries, I will just hand it to the dev whenever i feel it is stable enough).

edit: forgot the github address for those who wan to test it:

https://github.com/girino/spreadcoinx11-sgminer

edit 2: and the command line that gave me 2Mh/s:

./sgminer -o "http://127.0.0.1:41677" -u user -p x --thread-concurrency 8192 --lookup-gap 2 --auto-fan --temp-target 65 --gpu-engine 1100 --worksize 256 -I 22

I really want to use the improved miner ,but I have no ideas how to compile it. Angry
