The time I see missing is the time it takes NxCore to compress the data before it gets to you. And they might add some 'conflation'. Not sure what that time would be but wouldn't be surprised if on the order of 10ms and maybe higher. Really no idea though.
I do believe that IB's Fix interface was slightly faster. But that was 5+ years ago. Would be something you should test.
