Actually I don't think you're doing anything wrong. Mathematica just doesn't do binary file handling very well ---but if you use the Experimental Binary Import its much faster. <<Experimental`BinaryImport then commands like you used. It should be faster but still slow by any other modern program standards. I generally find Mathematica unsuitable for large binary files. It is orders of magnitude slower than its major competitor.
